Hello and greetings to everyone.I bought such a inverter https://powmr.com/inverters/all-in-one-inverter-chargers/powmr-1500watt-dc-12v-ac-220v-solar-inverter-charger/ I live in Poland and I am waiting for summer,Now winter and a short day with me.Maybe some of you have a similar inverter?

Can someone help me set the current for the 2x100Ah AGM battery.

Assuming that it's the 12 V model (the manual's URL has both 12V and 24V), so the two 100 Ah 12 V battery modules are in parallel, then you have effectively a 200 Ah battery. Generally lead acid likes to be charged at 0.15C, but AGM can often handle a little more, say 0.2 C.

So 0.2C x 200 Ah = 40 A.

I have no idea how to set the maximum charge current on your brand. Oh wait, the manual has finally loaded. Low and behold, this one appears to be a copy and paste from an Axpert manual. So setting 02 should be 40 A. At least without any more details on your AGM battery modules. Often, they will have the recommended charge voltage and current printed on the label. Double the current (as shown on each) since the battery modules are in parallel.

Edit: If however you have the 24 V model, and the two battery modules are in series, then you have a 100 Ah battery, and setting 02 should instead be 20 A, or the same as whatever is printed on the label (rounded down to the nearest 10 A, unless it's really close, like 28 A, in which case you could round it up a little to 30 A).

Thank you😀

You can see these screenshots if these settings are ok.

They seem OK IF and only IF your system is 12 V. You still haven't said if your two 12 V battery modules are connected in series or in parallel.

Hello falownik 12V connected in parallel. Battery 2x100Ah

I wrote you what I have an inverter. But maybe you know

 

Hello, maybe someone knows how to connect the Com output to your computer. I have a rj45-rs232 cable, and a rs232-usb cable. I plugged in and it doesn't work. Only wifi communication is ok
