Inverter/charger plus an extra mppt.

[Dtpmatt]

I have an all in one inverter/charger wired to my 48v battery bank but I would like to add an extra string of panels.

Is it okay for me to wire the extra strings mppt controller to the same busbar that the inverter/charger uses?

Many thanks in advance.

Yes

Yes

Thanks for your reply.

I'm was uncertain because when (for example) I use my AC I will be pulling quite a load through the busbar to the charger/inverter from the batteries. The Mppt controller (60a) only has a 5amp output and I'm nervous of frying it...

I don't understand this.

It's a 60amp charge controller but it has output +- that could power something small like a light bulb.

Don't use the output for charging the battery.
It has very limited use.

No. The output won't be used at all.
