And we welcome it's appearance

I'm actually really keen to see this in action. It also explains why it's a bit on the pricey side compared to other PWM controllers

There's honestly nothing special about it, it's just overpriced mediocrity and I don't see why it's more pricey.

I don't know about the PC board type but the box type,

Solar at the right on those 2 studs. Batt on the 2 wires already connected. Then there's 3 x 4 pin and 3 x 2 pin. And separate board with green and red led with 4 pin plug. Two wires with 4 pin both sides and one wire 2 pin both sides.

And again, I think it's super cool that (presumably) because it's connecting and interfacing with the board, it's going to show on the display when it's on solar, battery, or mains.

You need to open the inverter itself and take photos of the open plugs so that we can match them up

Apparently this and the box type is exactly the same. This one is cheaper because it doesn't come in the original casing.

Hmmm .... Not sure about that hey. The external one just plonks onto the battery terminals, while the internal one seems to connect to the internals and interface directly with the inverter. I think that makes the internal one superior, but certainly less user friendly to setup
 
I decided to measure the voltages of my 2 Hubble batteries. Battery 1 is 13.97v and battery 2 is 13.27. my Mecer 24v seams to think this okay. What do you guys reckon? Do I need to balance them? If so how would you recommend I do that? I have a fancy charger that can charge PB, should I connect it to battery 1 and charge battery 2?

Top balance = connect 2 in parallel and charge as 12V on a stand alone charger.

Switch inverter off. Connect fancy charger to battery 2 and charge until complete. Do the same for battery 1. Switch inverter back on.

or like @AlphaJohn suggests, rewire into parallel and charge together with fancy charger.
 
Awesome. Thank you guys. I'll give it a try. I think it will be easier for me to charge the battery 2 with the fancy charger. If it doesn't work then I'll rewire the batteries into parallel.

I do not have XP on Mecer + LiFePO4's so do not know if constant float ever fills em to full?

Cause If they never go full I would rather bottom balance than top balance. Only reason I top balance is cause I use Lead acid and dont ever go below 50%

Did you get the batteries as part of the same batch? cause it might be that they bottom balance, so top will give diff V readings.

LiFePO4's suffer from insta death if you run current through an empty battery.
