Ritar Power does give an Equalizing/conditioning voltage, it might be worth following their procedures to try to bring up the lower cells and perhaps get them sharing the load a bit better. http://ww…1 · -
Re: Hurricane hits off grid solar installation on remote beach which previously had performance issues
Most better battery charge controllers will have some method of data loging, This might help more to understand what is going on than anything. This sounds like an inverter shutting down to protect i…1 ·
