Re: FXR inverter firmware mismatch. Inverter 2 dissabled

GuerillaSolarGuy, I had this problem and got the solution on this forum. I replaced 2 existing inverters with 2 new VFXR3648 inverters in June 2018 when I fried one of my 2007 versions of the same inverters. A few months ago when the replacement inverters had been in service about one year without a...

Blue Ion 2.0 BMU charging and load following illustration

This graph illustrates the operation and performance of the Blue Ion 2.0 Battery Management Unit (BMU) reducing the charging rate on a decaying exponential, then very nicely matching loads until sunset while maintaining a full charge.

Yes, the VRLA battery Catch 22: The good thing about sealed lead-acid batteries is you don't have to maintain them like a flooded battery. The bad thing about sealed lead-acid batteries is you can't maintain them like a flooded battery. Very true. (VRLA = valve regulated lead acid? = sealed AGM). W...

Re: AGS Settings ?

Corndog, I'm no expert in AGS, and didn't use it for the first 11 years we lived off-grid. I implemented AGS when we upgraded our system and added an FNDC battery monitor. The FNDC-based AGS works very well using battery state-of-charge to control the generator to charge our Li-ion battery. We turn ...

My Flexnet DC monitor's state-of-charge tracks surprising well with the Blue Ion's system independent state-of-charge. I would de-energize the inverter at about 5 to 10% of battery capacity. My...

The charger function uses the inverter circuitry in reverse, de-inverting (is that a word?) AC current from the generator into DC current for battery charging.
De-inverting, aka rectification.

is there a way to get the generator to only power the charger, and not be pulled to serve the AC load?

Re: Direct DC charging of electric car?

Tesla Model 3 battery capacity is 75 kWh. 30 kWh of charging will get you 100 miles.

Getting large amounts high quality 240V energy off-grid is not straightforward with a normal off-grid battery bank and array.
