  • Another another Auto start Generator question

    Looking for a generator that will meet my requirements. Support responded with "The external device is the more appropriate term specially for generators with auto start function which can enter sleep mode and wait for wake up signal voltage." Saw a similar post, but it only had 30a I need 50a...
  • Thought I had enough power

    Bought two 6500w MPP 6548 inverters. 12 TrinaSolar 330W panels, and three 48v BigBatteries each 103Ah. Original plan was to power two campers off grid, One 50A the other 30A. Was told this system would be enough. Problem I have run into is lost power to the 30A camper, which is the only one...
  • High voltage battery arc

    Will has a video on YouTube that is 17 minutes, 27 seconds. DIY 13kW 48V Offgrid Solar System: How to build it from scratch! The exact system I just bought. Will shows using a power resistor crossing the 150a switchable fuse as to prevent the arc of the connection. Reviewing his video, he...
  • Anyone using a generator to charge batteries on MPP LV6548?

    Searched forum, and did not find any results. Have two LV6548's split phase. Have generator connected to input side. L1 and L2 connected, and even swapped connections from genny to L1 and L2. (Read somewhere that might help.) No luck. MPP's reset as if to sync with the AC, but never completely...
  • Clueless Smart guy

    I am the clueless guy. How do I determine which BMS will work in my battery? Someone mentioned to try a certain brand. I have 2 MPP LV6548's I can not find which specific BMS I need for my BigBattery Husky 48v. As I search, I find dozens of BMS's. Anyone know where I can find some
  • Bad Battery?

    Anyone have any thoughts on how to determine a Bad Battery? Or bad cells? Three nights in a row, about two weeks ago, my system died. Two MPP's LV6548. Three Husky Big Batteries (48v), Battery SOC was around 70%, and dropped to 10% SOC in less than an hour. My only diagnostic is Solar...
  • New build

    Tried to call supplier. but phone issues out west are not allowing calls through. Just purchased 13K system with 3960W of panels. Asked about adding a Victron Shunt, but they never responded. I see a 500A and a 1000A shunt. I am leaning toward the 1000A shunt. Which shunt do you recommend? In...
  • Curious if there is a need for 3 BigBatteries out there

    Have 3 Husky batteries. 48v 5.3kw batteries. About a hundred pounds each. I am in Florida, and want to change out for batteries that have a BMS that I can communicate with. Two are almost three years old, one is only a year old. BigBattery swapped it out because one battery failed.
