Do I need a 24 volt inverter?
Of course, you will need a 24 volt inverter (rather than a 12 volt inverter). Actually, you will barely be able to adequately charge one battery with a 300 watt panel. If you want to increase your battery bank, you will need more panels and a MPPT controller that can handle 50 amps.
How many watts is a 36V panel?
So, for example, let's say you put two 18V 100W panels in series, which will give you ~5.5A at 36V. You could then wire one 36V panel parallel to the string of two 18volters because they are both putting out the same voltage. How many watts is that 36V panel? Let's say for example that it is a 300W panel putting out 8.33A at 36V.
Can I replace 18V panels with 36V panels?
The panels will deliver 36v ". This suggests to me that you could either be removing the 18V panels and replacing them with an unknown number of 36V panels, or alternatively adding new 36V panels along side the original panels. Both are still doable, but with caveats mentioned above.
How many watts can a 36V controller charge?
So, your two parallel strings would be 5.5A at 36V and 8.33A at 36V, for a total of 13.83A at 36V. That is equal to 498W of panels total. 498W/13V charging = 38.3A. So, that combination would be OK for your controller, because the max amperage is less than 40. Now, what if you have three 18V panels?
Can a 300 watt panel charge a 24 volt battery?
Actually, you will barely be able to adequately charge one battery with a 300 watt panel. If you want to increase your battery bank, you will need more panels and a MPPT controller that can handle 50 amps. NOTE: the same controller that can handle a 300 watt panel with a 12 battery will be able to handle 600 watts with a 24 volt battery.
How do I protect my solar inverter from over-current?
Also, I connected a 7.5 DC fuses in line with each one of the solar groups to protect them from burning due to over-current. In addition, I bought a 1.5 amps AC fuse and mounted it into the 13Amps plug to protect my inverter from over-current and electrical shorts in the house. I Secure the 1.5amp fuse in by small pieces of the melted glow.
