Independent GivEnergy support that actually fixes the problem.
Battery not charging, portal offline, red light flashing, CAN comms fault, CT clamp errors — we diagnose GivEnergy systems at the engineering level. Remote-first. Evidence-led. Independent from GivEnergy and from your installer.
Common GivEnergy problems we diagnose
Every fault below has a proven diagnostic path. Click through for the specific page or book a diagnostic if you’re unsure.
Charge windows look correct but battery stays empty. Octopus Intelligent, Agile, and Go tariff configuration errors. CT clamp misread causing the inverter to think demand is already met.
See diagnostic guide →Inverter loses communication with battery over the CAN bus. Firmware mismatch, termination issues, cable faults, or BMS lock state after a protection event.
See diagnostic guide →Flash patterns on the GivEnergy battery indicate different fault states — BMS protection, over-temperature, cell imbalance, or communication loss. Do not open the unit.
See diagnostic guide →App or givenergy.cloud shows no data. Could be local WiFi loss, a GivHub hardware fault, a cloud-side outage, or a firmware update that broke the cloud connection.
See diagnostic guide →New router, changed password, or first-time setup. GivEnergy loggers require 2.4GHz — many problems stem from 5GHz-only or band-steering routers.
See setup guide →GivTCP, givenergy.cloud, Home Assistant integration, or API access configuration. We set up monitoring correctly or recover a broken configuration.
See setup guide →Inverted readings, backwards battery behaviour. Most-missed GivEnergy installation error.
Guide →DNO cap not applied, wrong limit, or limit resetting after firmware update.
Guide →House goes dark in a power cut despite having a battery. EPS disabled, wiring issue, or low SoC threshold.
Guide →System behaved differently after update — schedules broken, monitoring stopped, new fault codes appeared.

GivEnergy Warranty Support
We compile diagnostic evidence to strengthen warranty claims and support formal escalation to GivEnergy.
Warranty claim support →Tariff Optimisation
GivEnergy works well with Octopus tariffs — when set up correctly. We configure charge schedules and dispatch settings to maximise savings.
Tariff optimisation →GivEnergy Health Check
Full performance audit — compare actual vs expected output, check firmware, validate configuration, identify latent issues before they become faults.

GivEnergy is one of the UK’s most popular solar battery brands, known for their hybrid inverters, All-in-One units, and modular battery stacks. Their systems communicate over a CAN bus between the inverter and battery — a common fault path when communication breaks down after firmware updates or power interruptions.
The GivEnergy portal (givenergy.cloud) and mobile app rely on a local GivHub or WiFi module. When this loses connection — due to router changes, firmware bugs, or hardware failure — the portal goes dark even though the system may still be generating.
GivEnergy systems work particularly well with Octopus Energy tariffs (Intelligent, Agile, Go) when configured correctly. Many reported issues with battery not charging on cheap rate trace back to incorrect charge window settings, CT clamp orientation errors, or SoC minimum thresholds.

GivEnergy questions answered
Most common causes: incorrect charge window schedule, CT clamp direction error, BMS communication fault, or SoC minimum threshold set too high. See the full guide →
Local causes include router change, WiFi password update, or GivHub hardware fault. Cloud-side causes include portal outages or firmware that broke cloud connectivity. See portal offline guide →
A red status light typically signals a protection fault, BMS alarm, or communication error. Do NOT open the battery. Note the flash pattern and check the app for error codes. See red light guide →
Yes. CAN faults are usually caused by firmware mismatch, incorrect termination, CAN cable damage, or a BMS lock state. Many can be recovered remotely. See CAN fault guide →
EPS must be explicitly enabled in settings. It also requires a dedicated EPS output circuit and minimum battery SoC threshold to be met. See EPS configuration guide →
