This seems like an easy question but I think I have been scammed. I bought two of these and when I was looking over the text on the box I noticed a huge problem.
I have checked the download data sheet on this and it confirms what I think.
The official name of the controller is 100/20 48. The official name of a similar model line is 100/15 and 100/20.
Those two lines will handle just what the title says. 15 amps at 12 or 24 volts. 100/20 specs are 20 amps at 12 or 24 volts.
But the 100/20 48 appears to handle 20 amps at 12 or 24 volts but only 1 amp at 48 volts. So I bought two of these to run the 4 batteries in series at 48 volts.
But now I am going to have to scale my system down to have two panels that only produce a maximum of 1 amp in full sun.
Panels like that are going to be a lot smaller, many 12 inches by 12 inches.
You would think that the name of the product 100/20 would mean you could run panels like mine that produce 8 amps at 39 volts. But no, 1 map max.
I would appreciate any help on this as I am new at the solar electronics and there seems to be a lot of different ways to connect something. I bought a Victron mutiplus 2 3000 that is 48 volts. I did notice a slight problem on that inverter. It is rated for 3000 watts. I am installing this in a motorhome. With those specs you would think that you could run a 3000 appliance from this inverter. Right? Wrong! You may not be able to do that. Let's say you are planning to use this in the summer. Then you have to derate the the max wattage. If it is 104 F outside you can only run 2200 watts. This year is was 112 F here in Idaho for many days. That would mean you are down below 2200 watts for the max load. Maybe the max would be 2kw from a 3kw inverter.
You could move the inverter into your living space and put it by the air conditioning but now the ac would have to run longer.
This is all explained in the fine print on the data sheet. It is not explained in the marketing hype you usually see.
Victron seems to be the big name brand for solar but with these two things cropping up I am not sure this is the way to go.
