Hi,
Just got my new inverter. It will not charge the batteries when I supply 240vac input to do so. Or if it is...its very small. I have no desire for automatic, just need it to charge when I power it. I have set all battery specs for my Renogy AGMs. Is there a special setting to make it work? Do the the charge limits need to be set higher? I have seen many articles about modes. Is this related? I dont see that multiple selection other than basically operational or standby.
Appreciate your help!

Do you have a Combox or SCP to change the settings from the defaults?1500W, 6× Schutten 250W Poly panels , Schneider MPPT 60 150 CC, Schneider SW 2524 inverter, 400Ah LFP 24V nominal battery with Battery Bodyguard BMS

You should be in Advanced settings. Did you enable the charger and check AC settings?
Push the 3 left buttons at once to enter advanced settings. It is in the SCP manual."we go where power lines don't" Sierra Nevada mountain area

Lets say you have an 80 Amp breaker (on your 120/240 VAC circuit)... I like to suggest derating to 0.85 of rated wiring and breaker branch circuit capacity:
- 80 Amps * 0.85 NEC derating for continuous current = 68 Amps suggested max continuous load on NEC rated circuits.
You should check the battery mfg's manual... It is always best to use their (charging voltage, charging current, etc.) specifications.
However, charging at ~10% to 20% is a typical starting point... And if you decide to change the charging current in your SW--Make sure you check the setup instructions/LCD menu closely.
Sometimes, the Max charging current is that feeding the battery bank (24 volt bus in this case). But sometimes when you set limits, it is the AC current instead (say 120 VAC circuit).
So, for your battery bank... 20% of 200 AH battery bank:- 200 AH * 0.20 = 40 amps suggested maximum
- 40 Amps (battery current) * 29.0 volts absorb set point * 1/0.80 typical PF/Eff derating = 1,450 VA charging
- 1,450 VA / 120 VA = 12.1 Amps @ 120 VAC input (for limiting max charging current, not for limiting because of AC breaker limit)

Bill the CSW is a 30 amp breaker. XW is 60 amp AC the industry standard. To get more current you would stack inverters."we go where power lines don't" Sierra Nevada mountain area

No problem Dave... I was trying to show how the math works.
As always, refer the the manuals when working with the equipment and batteries.

I know good job! When in doubt read the manual"we go where power lines don't" Sierra Nevada mountain area
