Straight up garbage! It does not shut off and save the battery on the vehicle automatically, the dip switch settings are bogus I had to solder out my dip switches! What a waste of time and money! With my lithium iron phosphate battery sometimes it'll charge up to 13.1 volts sometimes it won't go past 12.5, according to Specs it's supposed to go to 14.4 volts. The only thing that's good about it is I can pop the hood, turn the breaker on, and charge while I'm driving so on days when there's no sun I can still keep my fridge running in my camper van, it will suffice for now until I get my victron set up going instead

Unit failed after 70~ days. It is trying to output current via the small xt60 solar plug and discharging both the cranking and the auxiliary batteries at the same time. This has been tested and confirmed with a clamp meter and temperature gun, the solar panel gets ROASTING hot when plugged into the charger at night in the dark. The dip switches also no longer switch between voltages, the unit is stuck and refuses to charge from the alternator at all. Customer service is refusing a refund after providing video evidence of the fault saying it is perfectly normal for the charger to dump current across the solar panel and flatten your batteries instead of charging them.

Voorlopig één ster, deze doet het niet helaas.

I'm not happy with it, i was hoping that it would turn off and on with either an ignition input or voltage when the engine is operating, but it appears you have to use the switch on the unit to turn off and on?

Werkt niet komt maar 12,6 volt uit en krijgt 14,5 volt binnen solar aangesloten komt 19 volt in komt 12.6 volt uit .in de nacht als er geen solar is gaat de lader uit de start accu omvormen om de licht accu te laden zodat ik in de ochtend een lege start accu heb .

Ostin tuotteen ja se ei toimi oikein, eli viallinen tuote. Kyselin ratkaisua asiaan, mutta sitä luvataan tutkia ja lupauksia riittää jatkuvasti, mutta mitään ei tapahdu ja kohta mennyt 2 kuukautta!! I bought a product and it doesn't work properly, i.e. it's a defective product. I asked for a solution to the issue, but they promise to look into it and there are lots of promises all the time, but nothing happens and it's almost been 2 months!!
