ROCKSOLAR 40A MPPT Solar Charge Controller

Sent wrong item

I ordered the POW-Keeper1240 MPPT, which I already had bought previously. They shipped me a different brand called POWMr 60amp which is not what I ordered and retails for less than I bought the item for. Not 100% of the process for exchanging or whether I should keep the unit they sent me as I needed it for a trip, it just messes up with wire set up.

Works great

Does the job as designed

Does not work
