I have now bought three of these here in the UK. There have been reports on the forum of people receiving units with cells without clear markings/QR codes. I've opened two of mine and they've all had clear factory QR codes. The cells are from 'Great Power' and even the third unit that I ordered several weeks later appears to have cells manufactured on the same day. The BMS is from JBD and after a lot of trial and error I found the appropriate Windows software that allows you to monitor and tweak the settings on parallel packs. The only issue I had is that with the batteries and my Solis inverter set to 'PYLON' as the protocol, the inverter threw an error for 'battery name'. I eventually tracked this down to a field in the BMS settings and was able to update this to what the inverter was expecting. No issues connected over CAN since. Once I tweaked my charge voltage, they charge well, although some cells are a bit out of balance and the voltage spikes on them at a high state of charge. I now have this under control and the passive balancing is slowly doing it's job. An excellent choice if you don't mind tweaking a few settings and learning as you go.
Full review / responsesReceived quickly and in perfect condition. I do not have the WiFi so doing everything through the buttons is the pita you expect but they work. If you don't have a smart battery it can't be set to LFP and soc is not accurate. Not silent but definitely not loud. Two issues I've experienced. First minor, the PV voltage and watts displayed are not stable. The numbers bounced around all over the place from an array that is stable on other devices. 120v 1320w but the display will vary from 40v to 120v with no change in sun. Second really annoying, if you disconnect the battery then reattach it won't power on. I have to plug in AC input then it will turn on. Did this every time like when I put in a smart shunt and when I installed a fuse. Parasitic draw is about 35w
