Inverter Charger not working

A place where users can meetup with other FlexPower One users and can find support for one another. A great place for people who have not purchased the FlexPower One yet to look up information.

Inverter Charger not working

Post by Grace Island »

We're experiencing a power failure. The system won't recognise gen input to charge batteries, and is not inverting 48v>240v) either The LEDs on the inverter/charger are not illuminated . The mate 3 is showing battery at 47.9v.

I can't seem to find anything in trouble shooting. Can anyone help?

Are you in the Philippines?

Is it a VFX or VFXR inverter?

What is your generator? Is it a Inverter Generator? Is it a 60Hz generator?

Did generator ever work with FlexPower One prior to this power failure?

Does your generator go through a Transfer Switch? Is there 220 VAC coming out of Transfer Switch and going into the Inverter AC Input L1 & L2 terminals?

No LED lights means "NO AC" present, so your generator must be the trouble. A VFXR Inverter has a setting in the Mate3 for lower quality generator output, while the VFX does NOT, and then must have the higher quality AC of a Inverter Generator.
