Helpful Hint with Sol-Ark hybrid inverters: Unlike most string inverters – Sol-Ark hrybid inverter solution will not have a complete power loss for a series string of modules if one of the panels goes bad (stops producing) *** so as long the total voltage of the remaining panel meets or exceeds the min mppt voltage range of 150VDC.
The eFlex 5.4 kWh 48 Volt Lithium Iron Battery by Fortress Power is a safe, scalable solution for any projects energy storage needs.
With built-in data storage and Wi-Fi for remote troubleshooting and monitoring. The eFlex is light years ahead of the pack. Additional features, such as the smart Battery Management System (BMS) includes relay disconnects, closed loop communication for many hybrid inverters, cell voltage and temperature monitoring, and cell balancing to maximize reliability and longevity, as well as wifi for internet-of-things compatibility.
