I installed one of these Seplos BMS 3.0 modules on my ~330 Ah, 16s LFP battery. It was easy to install, the screen is super informative and best of all, it does communicate with the Goodwe 5048 ES hybrid inverter. Sort of...
Up until now I've been using a completely independent BMS from EV Power which just opens a contactor if a cell went out of spec. I'd have to manually reset it, which got old... But, it meant that I was able to get the full 17 kWh from my battery.
After installing the Seplos BMS, I had two protocols I could select from - Pylontech and Goodwe, or rather, Gssdwe, as the case may be - gotta love hard-coded Chinese typos!
I've tried both, but so far only the Pylontech protocol works the most flawlessly. I have selected the US3000C*4 option in the SolarGo app. But, this implies about 12 or 13 kWh, despite the fact I have at least 16 kWh, maybe even 17 kWh available. No larger batteries available to choose from it seems.
Is there a way of changing the BMS to tell the hybrid inverter I actually have more capacity here? I mean, 12 kWh is good, and it will probably last 100 years at this sort of rate, but I feel like I'm being short-changed.
Any advise welcome.
