What size array can I use with my solar controller and how many amps will I get out of it?

Posted by Frank Molina, Stellavolta on Apr 17th 2026

Let's assume that your solar charge controller is 60A. Then multiply the solar controller's amps by the Average Battery Voltage for your size battery bank. 12V: 60A x 13.3V = ~800W24V: 60A x 26.6V = ~

Can I connect a different number of solar panels on each string to my inverter?

Yes. If you connect a different number of solar panels on a string to a separate MPPT, the inverter will harness the full power of those strings because they are on separate MPPTs. However, if your in

Should I be able to read voltage on the output battery terminals of a charge controller when I only have a solar panel connected to my charge controller?

First off, connecting only a solar panel to your charge controller is not safe and can damage your solar controller. If you only have a solar panel connected to your charge controller, you will not s

What is the difference between an SLA battery bank and a lithium battery bank?

Lithium Phosphate (LFP) batteries, like the Fortress Power eFlex 5.4 G2 Lithium Solar Battery 5.4 kWh or the Fortress Power eVault Max 18.5kWh LFP Battery Storage, can be discharged up to 90% without

Can I connect different solar panels to my string inverter?

String inverter manufacturers often recommend that you do not mix different solar panels to a single MPPT on one string inverter. Instead, you can sometimes place different solar panels on separate MP

Can the Morningstar TS-60 Charge Controller handle 2800 watts of solar going in to my 12V battery bank?

In theory yes, however it requires running the TS-60 at the full 60A rating, which can be difficult to achieve. The difference with the PWMs are...1. you cannot oversize the array. The array current M
