GivEnergy Charge Schedule Setup — Complete Configuration Guide

Q: How do I set up a GivEnergy charge schedule for Octopus Go?

For Octopus Go (cheap rate 00:30–05:30), go to givenergy.cloud → Settings → Timed Charge. Create a slot from 00:30 to 05:30 with a target SoC of 100%. Enable the slot and save. This tells the inverter to charge from the grid during the Go cheap window. Additionally, set up a Timed Discharge slot from 16:00 to 00:29 with a target SoC of 10–15% to use the stored energy during peak hours.

Q: Why does my GivEnergy charge schedule not work when it crosses midnight?

GivEnergy schedules use a single-day clock and do not automatically span the midnight boundary. A slot set from 23:30 to 05:30 will only run until 23:59 on the first day — it does not continue into the next day. To correctly set a charge window that crosses midnight, create two slots: Slot 1 from 23:30 to 23:59 and Slot 2 from 00:00 to 05:30. Both slots must be enabled with the same target SoC.

Q: Can I run Timed Charge and Timed Discharge at the same time on GivEnergy?

No — charge and discharge windows must not overlap. If a Timed Charge window and a Timed Discharge window are active at the same time, the charge instruction takes priority and the battery will charge from the grid rather than discharging to the house. Review all active slots across both Timed Charge and Timed Discharge to ensure there are no overlaps. A common mistake is having an old charge slot in the afternoon that was never removed.

Q: What is the difference between GivEnergy Timed Discharge and Timed Export?

Timed Discharge sends stored battery energy to the house — reducing grid import during peak hours. Timed Export sends stored battery energy to the grid at the export rate — earning SEG payments or taking advantage of high export periods (e.g., Octopus Flux peak export window). If you want to power your house from the battery, use Timed Discharge. If you want to sell stored energy back to the grid, use Timed Export. Running both simultaneously is not recommended as they conflict.

Getting your GivEnergy charge and discharge schedules right is what turns an expensive battery into one that actually saves money. This guide covers all four schedule types — Timed Charge, Timed Discharge, Timed Export, and Eco Mode — with exact settings for the most common UK tariffs, the midnight boundary rule that catches everyone out, and how to prevent schedule conflicts from breaking battery behaviour.

I have a GivEnergy system consisting of two batteries, two inverters and a controlling EMS (Energy Management System) which has not worked since Nov 2025. After six months I discovered Solar Tech Support, reached out to them and Ron phoned me back – how often do you get that service? Could not be more helpful – worked directly with me over the phone, outside what I would call normal working hours. Lucid explanations and we were able to discuss the issues and history using camera and email history. As this was a very rare setup, Ron was able to access an EMS expert in the field to confirm the solution. One sunny day in, I am now only paying for standing charge and a few pence for spikes in grid consumption while battery catches up with house demand.

When my GivEnergy system had an issue, I was completely left without support and had honestly lost all hope. Thankfully, I searched online and found Ron, which completely turned things around. After sending him a message, he responded incredibly fast and called me to assure me that he would get the problem fixed. I really admire his dedicated, supportive nature and his determination to find a solution. With this kind of outstanding attitude and customer service, he has absolutely secured a future customer in me.

Ron want out of is way to help, nothing was to much. He was very thorough in what he did Very knowledgeable I would highly recommend Ron and his company He did a fantastic job for me. if you have any problems, he'll do his best to help you out and resolve your problem. I wouldn't hesitate to recommend them

Dennis Brown · May 2026 Trustpilot

Ron took me through a diagnostic to confirm my GivEnergy Inverter had a fault. A common one as it turns out with the AC Inverter. As GivEnergy is defunct there is no immediate fix, aside from sourcing 2nd hand replacement. It may be that a fix becomes available over the summer which would make a lot of GivEnergy customers happy (Again)

Tony Deacon · May 2026 Trustpilot

Contacted Ron with a problem and he sorted it out quickly with no problems at all. Very knowledgeable on anything solar/ batteries. I would recommend him to anyone

I've spoken to Ron a couple of times with issues with my Givenergy installation. Such a friendly knowledge guy very highly recommended. Thank you very much for resolving my issues

michael fairhurst · May 2026 Trustpilot

Contacted Solar Tech Support in desperation. After explaining the issues I had with my system a diagnosis was made and a solution proposed. Fantastic service, even contacted a manufacturer to arrange replacement parts for me. Great communications, explained all they were doing and what I had to do, clearly and precisly. Followed up to confirm all was ok. Excellent service.

Mr Machin · May 2026 Trustpilot

After GivEnergy went into liquidation, just my luck, my battery started playing up (internal board crashed). Contacted my installer - not interested! Found Solar tech support on a Google search. Sooo glad I found this company! Ron is extremely helpful and has plenty of experience. He soon confirmed what the fault was, and helped me to get my system up and running again. Now moved my GivEnergy account to Solar tech support, and will definitely use again if I have more issues. Unusual to find such a helpful company in these times, no morons reading scripts, just direct contact with the engineer.

Contacted Solar Tech Support when trying to understand what my Givenergy inverter problem might be and what might be my options. Received good/honest advise which backed up my thoughts.

Hugh Speirs · Apr 2026 Trustpilot

Ron is a super star. Two months ago my GivEnergy battery failed a firmware upgrade leaving it a brick. My installer couldn't/wouldn't fix it. GivEnergy couldn't/wouldn't fix it. Then they went into administration and all hope was lost. A flurry of emails later and Ron had diagnosed the fault (failed USB flash drive, something I'd suspected) and talked me through resolving it. Two months of nothing resolved in about 3 hours. It's great to work with someone who pays attention to the details, knows that they're doing (not just following a script) and gets stuff sorted without a fuss or up-charging.

Christopher · Apr 2026 Trustpilot

I can add to the list of customers who had already 'given up' on GivEnergy due to their appalling customer service, and that was before they went into administration (their Trustpilot reviews don't lie!). So you can imagine my desperation when, having changed my ISP and my Inverter, predictably, proving to be the only device that didn't connect automatically to my new network, I found zero prospect of any customer support with GivEnergy having called in the administrators just five days earlier! The salvation came from Solar Tech Support. My IT advisor stumbled across their web site and some very helpful tips for beleaguered GivEnergy customers, as well as an offer to provide direct assistance. Nothing ventured, I decided to drop them an E-Mail, with very low expectations based on my experience of GivEnergy customer support. Within an hour Ron had responded with some pin point advice, and after a few exchanges of E-Mails he had nailed the problem, enabling the combined efforts of my IT advisor and solar installer to resolve it and reconnect my Inverter. Thank you Solar Tech Support, and Ron in particular, for coming to the aid of a deserted and despondent GivEnergy customer. Expert, razor sharp advice and first class customer service, even though I wasn't officially a customer.

This company are a rare gem, I had a very unusual problem following a failed firmware upgrade on my GivEnergy kit. I then found out GivEnergy were in administration and had dismissed all their support staff! None of the usual fixes to try and restore my inverter comms would work, and I looked everywhere, forums, GivEnergy youtube support videos - even AI couldn't figure it out. My installer was talking about huge sums for system replacements, and being vague / evasive about if they'd even install replacement GivEnergy inverter. Enter Solar Tech Support, reassuring and knowledgeable from the very start, I've learnt loads about my solar system though the friendly chat while my engineer worked as he diagnosed the problem and figured out a fix procedure that I've not found anywhere else - amazing . If you need solar system repairs - especially if you like me have been left high and dry by GivEnergy, I cannot recommend this company enough. Give them a call.

Andy Thomas · Apr 2026 Trustpilot

I sent a message on their website regarding a problem I have on my Givenergy system. Although not supplied by Ronald, I thought it was worth an email. Within the hour on a Saturday, he phoned and we discussed the problem. He logged in remotely and gave excellent advice. I'm too far away for his on-site help but he did diagnose the problem and was happy also to chat through my thoughts about an upcoming solar/battery install I'm planning. Great bloke.... if only he was nearer!

Overview

Modes

GivEnergy schedule types — what each one does

GivEnergy uses named modes rather than a simple charge/discharge calendar. Each mode controls a specific direction of energy flow. Most homeowners use a combination of Timed Charge and Timed Discharge, with Eco Mode during non-scheduled hours.

Timed Charge

Charges the battery from the grid during a set window. Used to fill the battery during cheap-rate periods (overnight, Economy 7, Octopus Go). Set a start time, end time, and target SoC. The inverter draws from the grid at full rate until the target is reached, then stops charging for the rest of the window.

Best for: cheap-rate overnight charging

Timed Discharge

Discharges the battery to power the house during a set window. Used to avoid peak-rate grid import in the evening. Set a start time, end time, and target SoC (the minimum the battery discharges to). The battery powers house loads first; grid makes up the difference if house demand exceeds battery output.

Best for: reducing evening peak-rate grid import

Timed Export

Discharges the battery to the grid during a set window. Used on export tariffs (Octopus Flux peak export, high SEG periods) to sell stored energy at above-average rates. The battery exports at its rated output rate. Note: the house still imports from the grid during a Timed Export window — the battery output goes to the meter, not the house.

Best for: Octopus Flux users, high-rate export periods

Eco Mode

Automated mode — the inverter manages charge and discharge based on solar production and household demand without fixed time windows. Solar surplus charges the battery; battery discharges when solar is unavailable. No cheap-rate charging or fixed evening discharge. Use Eco Mode outside of your Timed Charge and Discharge windows for best results.

Best for: daytime operation between charge and discharge windows

Timed Charge

Setting up Timed Charge — overnight cheap-rate charging

Go to Settings → Timed Charge in the portal or app

In givenergy.cloud: My Inverter → Settings → Timed Charge. In the app: tap the inverter → Settings → System Mode → Timed Charge. You will see up to 3 time slot entries.

Enter Start Time, End Time, and Target SoC

Start and End time should match your cheap rate window exactly. Target SoC is the battery level to charge to — 100% for a full charge, or lower if you want to leave headroom for solar in the morning (80–90% is common for systems with good solar production). If your window crosses midnight, see the midnight rule below.

Enable the slot toggle and save

The slot toggle must be in the ON position — a slot can be created and saved but inactive if the toggle is off. Confirm the slot appears in the active schedule list. The system mode will switch to Timed Charge during the window and revert to Eco Mode outside it.

Verify on the first night: Check the portal at the start of your charge window. Battery SoC should be increasing and the grid flow indicator should show import. If the battery is not charging, check the system mode is showing Timed Charge in the portal status and that no smart tariff connection is overriding the schedule.

Timed Discharge

Setting up Timed Discharge — powering the house from the battery

Go to Settings → Timed Discharge

Navigate to the same Settings area as Timed Charge. Timed Discharge slots are separate from Charge slots — both can coexist as long as their time windows do not overlap.

Set Start Time, End Time, and Target SoC

Start Time: when you want the battery to start powering the house (typically 16:00, after solar production drops). End Time: when you want the battery to stop discharging (typically 23:00 or 23:30, before your overnight cheap window starts). Target SoC: the minimum battery level to stop discharging at — set to 10–15% for maximum use, or 20–30% if you want to keep a small EPS reserve.

Confirm there is a gap between Discharge end and Charge start

Leave at least 1 minute between your Timed Discharge end and your Timed Charge start. If the Octopus Go cheap window starts at 00:30, end the Timed Discharge at 23:59 (or use Slot 1 of the midnight split). This ensures the inverter correctly transitions between modes.

Discharge target SoC: If you set the target to 50%, the battery will stop discharging when it reaches 50% and switch back to Eco Mode for the rest of the window. Set it as low as you're comfortable with — 10–15% is standard for homes without EPS requirements.

Critical — midnight boundary

Critical

The midnight boundary rule — the most common scheduling mistake

GivEnergy's schedule system uses a single-day clock. It does not support time slots that cross the midnight boundary in a single entry. If your cheap rate starts before midnight (e.g., 23:30 on Octopus Go), you must split the window into two slots. This catches out the majority of GivEnergy users on time-of-use tariffs.

❌ Incorrect — single slot crossing midnight

Slot 1:

Start: 23:30

End: 05:30

Target SoC: 100%

Enabled: ✓

This slot ends at 23:59 on the same day. The charge does not continue past midnight. Battery charges from 23:30 to 23:59 only — less than 30 minutes of cheap charging.

✓ Correct — two slots, split at midnight

Slot 1:

Start: 23:30 · End: 23:59 · SoC: 100% · Enabled: ✓

Slot 2:

Start: 00:00 · End: 05:30 · SoC: 100% · Enabled: ✓

Two slots with the same target SoC create a continuous charge window from 23:30 to 05:30, correctly spanning midnight.

Common mistakes

Avoid

Common GivEnergy scheduling mistakes

OVERLAPPING WINDOWS

A Timed Charge and Timed Discharge slot active at the same time — charge takes priority and the battery charges from grid during your intended discharge window. Review all slots across both schedule types for any time overlap.

SLOT CREATED BUT NOT ENABLED

The slot is saved and time is set but the enable toggle is off. The schedule view looks correct but nothing happens. Check every slot for the enabled indicator — it's separate from the save button.

TARGET SOC TOO HIGH ON DISCHARGE

Timed Discharge target SoC set to 80% when the battery starts at 85% — only 5% usable capacity. The battery stops discharging almost immediately. Set target to 10–15% for a full evening discharge.

SETTINGS RESET AFTER FIRMWARE UPDATE

Firmware updates can reset schedule slots to inactive. Always verify all settings after a firmware update notification — especially the enable toggle on each slot and the system mode setting.

FAQ

GivEnergy charge schedule questions

How do I set up a GivEnergy charge schedule for Octopus Go?

For Octopus Go (cheap rate 00:30–05:30): go to givenergy.cloud → Settings → Timed Charge. Create Slot 1 from 00:30 to 05:30 with target SoC 100%. Enable the slot and save. Since the window starts after midnight, no split is needed. Also set up Timed Discharge: Slot 1 from 16:00 to 23:59 with target SoC 10–15%. This fills the battery overnight at cheap rates and uses it to power the house through the expensive evening period.

Why does my GivEnergy charge schedule not work when it crosses midnight?

GivEnergy schedules use a single-day clock and don't automatically span midnight. A slot from 23:30 to 05:30 only runs until 23:59. Create two slots instead: Slot 1 from 23:30 to 23:59 and Slot 2 from 00:00 to 05:30 — both with the same target SoC and both enabled. This creates a continuous window across midnight.

Can I run Timed Charge and Timed Discharge at the same time on GivEnergy?

No — overlapping charge and discharge windows cause problems. The charge instruction takes priority and the battery charges from the grid during what you intended as a discharge window. Always review both schedule types to ensure their time windows don't overlap. A common mistake is leaving an old afternoon charge slot active that overrides evening discharge.

What is the difference between GivEnergy Timed Discharge and Timed Export?

Timed Discharge sends battery energy to power the house — reducing grid import. Timed Export sends battery energy to the grid at the export rate — earning SEG payments. During Timed Export, the house still imports from grid because the battery output goes to the meter's export clamp, not the house circuit. Use Timed Discharge to save on peak bills; use Timed Export if you have a high export rate (Octopus Flux, Agile high-price periods) and want to earn from selling stored energy.
