Unable to charge

Post by gpearce52 » Tue Sep 03, 2019 5:26 am

My Radian is qualifying the generator and passing power through to the house circuits but I am unable to engage the charger.
Is the battery charging dependent on a minimum voltage setting?
Any suggestions?

Thanks

What MODE is the charger set to? (On Mate3s, press the Charger hard key on the left, then select Mode.)

The AC Input and Charger AC Limit is set to something above 0?

Any errors showing on the Mate?

What's shown pressing Inverter soft key on the Mate?

What's on the Next (Inverter Battery screen)?

Dirty input voltage - Radian switches to battery

Post by dcbbow1221 » Fri Sep 06, 2019 6:11 am

Location: Puerto Rico. Input voltage fluctuation after 8pm (AST), constantly switches to battery., even though there is voltage. I am operating on Grid-Tied mode. I have the Inverter (GS8048A) in "charger mode". My overall objective is to sell as much PV to the Grid to offset my bill, saving battery bank for emergencies such as Hurricanes. The event history indicates a inpupt voltage of 228v. I am using about 28 kwh of grid once the system switches back. Other than bypassing the inverter at nighttime, what other option do I have? I tried using the MiniGrid mode and adjusting the cutover battery voltage, but am unsure of what voltage the batteries should be. I have 12 Outback baterries on 3 charge controllers.

If the voltage fluctuation is too great it will kick you out of grid tie mode. If you have a time of day that's know to be bad you might program the mate3 to kick over to minigrid for the bad hours then back to grid tied mode.

Thank you, that was my feelings also, I did do that, any suggestions on the cutover min battery voltage (this is where I get lost - 12 Outback batteries? I a on 3 charge controllers) m trying to reduce the drain on the batteries in order to prolong life. I had set it at 50. The problem is that everytime I draw down batteries, much of the morning uses all of the PV to re-charge. Goal is to maximize PV sell back to the Grid waiting for the next hurricane.
Thanks again.

What are you seeing when you press the inverter soft key on the mate?
