ok, i basically purchased this instead of getting an inverter and controller for my panels. quite convenient indeed and very easy to setup – i just basically hung it on the wall in the garage, connected it to my PV system and main panel and ran its standard program and voila. approved.

I think I saw something similar, but weren't there FM100-300VDC controllers instead?
09/02/2021, 09:11
Yes, you are right. However, FPR systems with FM100-300VDC are no longer manufactured and right now they are replaced with FM100-AFCI regulators.
what about fusing? Does it have any overcurrent protection?
08/19/2021, 10:17
Yes, it does. This model has two 175A inverter overcurrent protection devices.
Hi. Where would you recommend installing it?
08/02/2021, 11:06
Good day. Given the fact that it’s an inverter, the garage would probably be the best option. We would recommend a cold, dry, clean place out of direct sunlight.
so it’s an inverter box, right? does it support lithium batteries?
07/15/2021, 09:35
Yes, it’s an inverter box with charge controllers and safety switches. It supports lithium batteries.
