Bought this and can still return:

1. MOES Dual Power Controller 50A 5500 Watt Automatic Transfer Switch for Off Grid Solar Wind System ATS DC 12V 24V 48V AC 110V 220V.

2. GIANDEL 24 Volt 2000W Pure Sine Wave Power Inverter DC 24V to AC120V with Dual AC Outlets with Remote Control 2.4A USB and LED Display

3. EPEVER MPPT Solar Charge Controller 40A 150V PV Solar Panel Controller Negative Ground W/ MT50 Remote Meter + Temperature Sensor PC Monitoring Cable[Tracer4215BN]

Bought this and am picking up in 2 days.(Bought 48v instead of 24v)

48V 100AH LiFePower4 Battery by EG4

Should I return 2 and 3 and just go with

80A MPPT 250V Charge Controller by Growatt​

And 48 volt inverter​

Please hold the laughter.

I understand replacing the 24V inverter, but why would you upsize the charge controller? Going to 48V allows the charger to output twice the wattage as on 24V.

Does Growatt even make a charge controller? I believe that they only make AiO inverters, that have built-in charge controllers. So, there are several choices here...

1) replace the Giandel inverter with a 48V model, replacing nothing else.
2) replace the 48V battery with a 24V one
3) replace both the Giandel inverter and the Epever charge controller with the AiO Growatt (perhaps the SPF3000).

So, you have two degrees of freedom here.

The linked unit seems to indicate only 12/24V options.

The right 3 appear to be Growatt.

You were more thorough then me. Should have checked the link. I just assumed it was the Tracer because it was 150V.
