Basic Hardware Diagnostics You Can Check Yourself

Overview

This is a practical, at‑home diagnostic flow for GivEnergy systems. It helps you identify simple power or breaker issues that commonly cause batteries or inverters to go offline.

Important safety notes

Only perform basic visual checks and button presses. Do not open live electrical enclosures or rewire anything.
If any switch or breaker trips immediately after you turn it on, stop and contact your installer or GivEnergy support.

Check AC isolators (solar and grid)

Locate your AC isolators (typically one for the grid and one for solar PV).
Confirm each isolator is in the on position: the selector pointing straight up to the line.
If a selector is turned to the left (circle symbol), that’s off. Return it to on.

For systems with separate battery and inverter

Look at the battery front panel:

If there are no lights, press and hold the battery on/off button (front/right side) for a few seconds until you hear a beep; lights should come on.

Check the battery DC MCB (usually on the left side of the battery; some older systems have it mounted on a wall):

Unscrew the cover, lift the flap, and look at the switch.
Up is on; down is off/tripped. If it’s down, push it up to on.
If it immediately trips back down, stop and contact your installer/GivEnergy.
If you changed the DC MCB position, press the battery power button again to bring it online.

For All‑in‑One systems

Front power switch/light:

The switch light is normally blue when on. If it’s off, press and hold the power switch for a few seconds to turn the unit on.

DC MCB:

Open the flap; verify the DC MCB is up (on). If down, push it up.
If it trips immediately, stop and contact your installer/GivEnergy.

After restoring the DC MCB to on, press the front power button to bring the unit online.

If you have a GivEnergy Gateway (not all systems do)

Unlock and open the Gateway door.

Check the internal breakers/switches:

All four main switches should be up (on).
The “Bypass – Authorized Personnel Only” switch should be down (that is normal).

If any required switch is down, push it up. If it trips immediately, stop and contact your installer/GivEnergy.Check your home consumer unit (fuse board)

Check your home consumer unit (fuse board)

Look along the row of breakers/RCDs to see if any are down (off/tripped).
Push any tripped breaker up to on.
If it trips again, get a qualified electrician involved.

After restoring power

Allow 5–10 minutes for the system to fully reconnect (Wi‑Fi and monitoring can take a few minutes).
Recheck that battery lights are on and the system shows as online in your app/portal.

When to escalate

Any breaker or DC MCB that trips immediately after being turned on.
You restored isolators and breakers, but the battery/inverter still shows no lights or won’t power on.
Persistent faults after the above checks.

Following this sequence resolves many “system offline” cases caused by a switch or breaker being turned off or tripping.
