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?
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?
Yes, it does. This model has two 175A inverter overcurrent protection devices.
Hi. Where would you recommend installing it?
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?
Yes, it’s an inverter box with charge controllers and safety switches. It supports lithium batteries.
