I am looking to replace my mttp and inverter to this all in one system. My current mttp gets my solar cables in and has wires going out to charge the batteries. This all in one does not have that option it has just a PV input

Anyone has this unit and can share insight.
 
The MPPT inside the same box is essentially connected to the inverter main terminals such that the single set of cables connected to the battery provides both the power for the inverter and the incoming juice from the MPPT.

Thanks for the confirmation.
 
So that I understand correctly the battery cables connected to the inverter charge the batteries and pull the juice from the batteries- will this stop working when it charges as I’m off the grid no shore power.

No. It functions exactly the same way a separate inverter and MPPT would. They just have a common set of battery cables.

Check out this diagram:

See how I moved the MPPT output directly to the inverter terminals? This is basically how the PowMr works. There's still a connection to the battery through the inverter cables.
 
also be very much aware that powrmr is a clone of a voltronics / mpp solar aoi with cheaper internals.
please do search the forum because their support isnt the best either

So based on this version A of this rough diagram is correct

No direct connection of panels to battery.

Never. With this equipment or any other... unless you want to destroy the batteries, then it's cool.

This is how I have my current system - moving to a 48v system hence upgrading to a all in one unit - this might be more trouble if I don’t wire it properly- I watched a video by Will and he did exactly what I drew on A .
