Help

I'm new to Solar and have a 20x20 off grid cabin and would like to add more panels. I have 4-Lg 280-watt panels with VOC 38.80 and ISC 9.33 using a EPEVER Tracer 4215BN 40A 24-volt 150V. I have 8 100Amp hour Redodo Batties set up for 24 volt 3000 watt inverter.
I would like to add two more LG 280 panels and change over to a all-in-one inverter charger that can handle all six panels and batties.
If someone can give me any suggestions on a good 24 volt unit to use.
Thanks for the help

There are several 24V/3kW AiO that can handle about 2kW PV.

I just bought this one:

https://www.amazon.com/Inverter-Charger-Controller-Lithium-Batteries/dp/B096FG97DQ

It was $422 Black Friday.

I show a $40 off, so $445.

This is a typical Voltronics-type unit like MPP Solar, Growatt, older EG4 and Sungold Power units.

Curious what your current inverter is?

Why the move to AIO instead of just a larger charge controller?

For your scenario here, just getting an 80A charge controller would do it. Feed it with 2 strings of 3 panels.

I think my inverter is going bad, it's making a ticking noise and just wanting to be ready. Also change to one I can use with a service panel instead of cords running around.

The Growatt 3kw has been pretty tried & trued unit for a long time, and can take 2kw+ in panels. You can re-use your existing SCC for more panels when you get over your limit.

Midnite MN5048DIY.
Reconfigure your same batteries to 48v.
Series all your panels.

Just an idea....

The PowMr is a SRNE rebadge. SRNE has a license to use Voltronic patents, along with their own, but they build their own units. I have been running the one Mr SE linked to. It has been without problems now for about 8 months. It could be set up with the 6 panels in series since it has a 450Voc ability (needs 120vDC minimum to operate) which simplifies things for your array.

I have a review of it in the AIO Forum somewhere from last year. Please understand that I do not endorse any equipment. Do your own research before making a design decision.

Thanks for the info.
