Advice please on adding new panels and charge converters over maximum rating.

Adding new panels and charge converters.

Good evening from a warm Mullion Cove Cornwall : )

I am about to add 6 x 415w panels in series pairs keeping the system at 12 volts to start with.

Later on the 2 x 3000w Renogy inverters that are 12 volt only, will be replaced by 24 or 48 volt ones.

Given that these charge converters will stand 1.5 times the power, and that the 415 w panels facing south may never reach their maximum output, would it be safe enough to run at 12 volts for now ?

Quote from advert (The XTRA tracer models have a current limiting function, you can connect 1.5 times the rated power to the controller)

For 12V Solar System: 520W solar panel (150V for max input voltage)


For 24V Solar System: 1040W solar panel (150V for max input voltage)
For 48V Solar System: 2080W solar panel (150V for max input voltage)

So each charge converter will have two 415w panels in series connected to it.

Once I change over to 24 or 48 there will be no problem.

I have 4 x 12 / 24 v 40amp charge converter at the moment, with two 340w panels in series connected to each one, this has run for a year or two with no problems.

Thank you for you advice God Bless

Don't exceed max Voc (temp adjusted) and max Isc, and you should be fine.

Thank you DIYrich,

I will order one, connect a couple of the 415w panels in series to it and feed it to the present 12 volt system.

We have some very sunny days at the moment, so if it will be a good test : )

God Bless Chadd
