Actually, I solved it. There was an Eaton 63A fuse on the inside that blew. It must have exceeded 63A on the input as the unit tried to pull infinite amps (near zero ohms) through the short circuit for an infinitesimally small amount of time. So the input fuse failed faster than both the input...

Hi all, I have two LV6548's running in split phase. Been running fine for 6+ months. No solar input (yet) - just battery and AC input. The units run in bypass most of the time, but if there's an outage, batteries provide power. All working flawlessly. However, I now have a weird issue where...

Hi - did you happen to find out what happened, and how you resolved it? I have exactly the same setup, and just had the same thing happen to me, and I have no idea why the unit that is showing zero won’t detect the input. Tried cold restart, etc - nothing changes. Everything else works fine -...

Actually, solved it - there is a fuse inside. See my other post for details (if anyone else comes across this): https://diysolarforum.com/threads/mpp-lv6548-ac-input-issue.69723/ Thanks! Z.

Hi all, I’m new to charging Li-ion with a BMS. In the past I’ve always assumed a special charger is needed, but from my research it seems that to charge a 14S string of 3.7/4.2 Li-ion batteries (51.8/58.8 combined) with a 100A Daly BMS attached that I just need any power supply that can supply...

Thanks John! Just a follow up question… I thought the BMS will stop any charging from happening when one of the cells hits 4.2v? If so, doesn’t that terminate charging? Basically I’m trying to find the easiest way to fully bench charge these two 51.8/58.8v battery packs I just got (comprised of...

Actually I just bought an 8A 58.8v CC/CV li-ion charger with OCP/OVP/OTP built in. Thanks again for the help! Z.
