Building a off grid / grid assist system with 2 LV6548 and a bank of 6 EG4 48v batts
using 48 used 250 watt panels. planning 6s2p for 3000 watts to each of the 4 mppt inputs 12kw total
I have a few questions on fuses etc
1. T fuses between inverters and batteries..should I be using 200 amp or 300 ?
2. I have 4 strings of panels, I need 4 dc breakers at 30 amps, what are a lot of you using for this ?
3. A/C input, the inverter manual seems to call for 4ga wire for AC input and output. how many amps are being fed in ? and how is it divided to serve both LV6548s ? separate breakers and wires to each inverter from the main panel ?? should I install a a/c disconnect for the ac input ?
4. what is a shunt ? and do I want or need one ? Ive seen smart shunt that sends battery info
thanks for any advise
