IdSwitch - max solar power input possible?

[melw1]

Hi,

I’d like to increase the solar on our new MH from a single 100w panel to as much as the IdSwitch controller can handle safely, I will have a 300w lithium battery. The dealer is sorting this for me prior to collection of my new to me MH. (I don’t really want to install a separate solar / battery system).

The IdSwitch user guide states Max Open Circuit Voltage of 25 VDC and max supply current of 15A. So using the formula Power = Voltage x Current this makes 374 watts. If I remember correctly, my dealership is saying we can only install 200 watts as that’s all IdSwitch can cope with. However, we have solar at home, and we’re used the the concept of overpannelling / clipping. Does this principle apply to MH systems? If so, is it save to put on 3x100watt panels instead of 2 (in parallel?).

Many thanks in advance.

Don’t worry - have found another IDSwitch manual that states categorically 200w only.

I’d argue you’ll need more than 200W and a B2B if you haven’t got one already fitted to keep the battery charged fully

Not sure what your controller is but I’d also bin it for a Victron one or have a separate system altogether
