EG4 LifePower BMS and Signature Solar Support Issues

[Jriccisf]

If they aren't working right they should be taken back by sig solar for a full refund imo. Asking for weeks or months of babysitting to get things back into balance should not be the responsibility of the purchaser.

Exactly! @SignatureSolarJess @EG4_Jared - what's your take here?

That’s definitely not what I want to hear

Here’s the thing - these systems are remote, off grid installations. It’s impossible for me to babysit a deep cycle process for 14 days. I also can’t bring the whole system down just so I can deep cycle one battery. It really feels like this is a battery malfunction or the result of a poorly designed battery/BMS system. End users should not be required to go through such lengths to get a battery to function properly. It’s also incredibly frustrating to not be able to get reliable support from the vendor or manufacturer.

Anyway - is there any way to complete a deep cycle process with the chargeverter?

Take the battery home and use the CV to charge up to 55v. Disconnect the CV DC breaker and let the battery rest for 8 hours. Rinse and repeat. Keep track of the cell voltage. If you have a Windows PC available, use that. Windows app shows when cells are balancing.

If the unit goes through troubleshooting and is deemed defective, we will of course be replacing it!
