I have had a solar electric system for over 20 years, but for the last few years I have been planning for and implementing a much-needed upgrade. I have been working to install an MPP LVX 6048 and Battle Born 12v 100Ah batteries. After purchasing all of this, I am being told of requirements that I wasn't aware of. First it was the minimum voltage from the PV array. I knew there was a max voltage, but didn't know the minimum. I added panels and rewired the array to get it over the 160v I was told was the minimum. With that done successfully, I started installing the rest of the system. I am now being told that the battery back has to be at least 300Ah and 400 recommended. Otherwise, the batteries cannot charge the capacitors in the inverter. With four 12v/100Ah batteries in series, I have the 48 volts I need but only 100Ah.
I have looked and looked and I cannot find anywhere that these requirements are documented, other than the emails from the place I bought the inverter.
Is this correct? If so, I guess I either need to buy a different inverter, add substantially to my investment in batteries, or buy different batteries altogether.
Thoughts and suggestions appreciated.
