Hi, I have 3 AIO with gateways on a site that are working as big UPS’s. (No PV).
1 worked perfectly straight away after commissioning.
The other 2 are currently showing a 0% SOC, and appear to have stopped charging.
Does anyone know if there is a way to force a charge (i’ve tried turning eco off and scheduling a charge from the grid, and that didn’t work). Or do the packs need a manual charge before the system will kick into life again?
If they are online and not silly flat, the service desk can look at them.
They will need the serial number of the 2 that need help.
If the batteries are suplied flat, then there maybe a reason to go back to the wholesaler and get replacements, as they should maintain rotated stock. Batteries on the shelf after many months will self discharge.
If you want to attempt to charge these on site saving you some time, then you will need a charger capable of charging 80V and at least 3A
If you have this, I can supply you instructions to locally recover each pack to 75V each. Enough for the Battery management system to turn on
Appreciate your reply. They were OK when supplied. After they first discharged it looks like they didn’t have the right settings to charge back up from the grid, and it wasn’t spotted for a few months.
We’ve got a QDD 87.6v 5A LiFePO4 smart charger. Will that do it?

Here is how to do it
Amazing thanks
