Read: How to Monitor Voltronic Inverters and UPS via WiFi →The InfiniSolar WP HB 10kw works with a 720 VDC/900 VDC bank. It charges at up to 30 A, and that current — not the bank's capacity — is what the cabling and the fuse between bank and unit have to be sized for.
Peak efficiency is >96%. Whatever is not converted leaves as heat, so the InfiniSolar WP HB 10kw needs clear air around it and a mounting spot that is not the hottest wall in the building.
Over RS-232, RS-485, USB, CAN and Wi-Fi. Those are the ports this unit publishes, and any monitoring or logging you plan has to go through one of them.
