Finding a low-frequency (toroidal) inverter that meets my needs given the models locally available to me in Thailand has been extremely difficult, and I'm beginning to feel it may be impossible. I've been searching/researching for days, and have considered many models, only to be disappointed...

I'm finalizing my design, and already have two EPEVER Tracer 8420AN units planned to handle one string of panels each in conjunction with an LVTOPSUN inverter on a third string of panels with all three connected to a 51.2V, 280Ah LiFePO4 powerwall battery. As I'm studying the manual for the...

The schematic is not perfect due to limitations of the design software used, but imagine that each of the breakers for the PV arrays is connected to both positive and negative cables, i.e. a dual breaker. The fuses would just be on one line as shown. One of my concerns with having parallel...

I've been eyeing the new-style double-hole (two-screw) terminals for the prismatic cells in the 280Ah - 320Ah range as these should form more secure connections. Today I was told by one of the reputable sellers on Alibaba that there are no DIY cases for a 48-volt system (16s) available for the...

Wood doesn't last well in my climate. Cement board doesn't seem designed to carry much weight. Plywood, if obtainable, quickly falls apart in the humidity. Concrete walls exist, but are not very portable. The whole system is expected to be moved to a different building within two years, so...

In attempting to achieve communication between the inverter and the battery, I connected a standard Cat. 5e patch cord between the sole RS485 port on the 3KW LVTOPSUN inverter and one of the several ports of this same label on the JK BMS of the 48V, 280AH LiFePO4 battery. The magic smoke was...
