    Wisdom/BSL battery, Sigineer inverter, Jinko Tiger Pro, and RoofTrac install in Belize

    A year ago I was researching and planning. I settled on Wisdom/BSL 10kWh 51.2V LFP (6 total), Jinko Tiger Pro 530W (pallet of 31), Sigineer 230V single phase 5kW off grid inverters (4), Victron auto transformers (2), and various glue parts and mechanicals. In September I got Belize PUC...

    off grid home system - comments on some details...

    I am pretty comfortable with the system on the right (rooftop panels, inverters, battery, etc. I am also pretty comfortable with the little remote power system on a 20' container for outdoor power. It makes sense to put the generator in the ventilated container and it makes sense to also use the...

    are 96V LiFePO4 a good idea?

    Seeing 96V charger inverters out of China and thinking this is an emerging trend... Allows higher MPPT efficiency for long strings, so reduced copper needs and reduced copper losses. EG 3s and up 144 half cell systems with 120V+ Vmpp would readily charge 96V banks and 96V would be more...

    possibly naïve question on integrated MPPT solar inverters (off grid, DC coupled)

    I have been working out the basics but I am a little baffled by this: 9600Wp system (for example) to a 48V battery must be providing 200A to the DC coupled node but these systems all have max charging current well under 200A. Should I assume there is a 3-way FET or IGBT coupling so that the...
