RV FEATURE
The Bluetti Charger 2.
DUAL CHARGING
Does the dual charging input actually work? Again, yes is the simple answer. I was only able to get a maximum of 640W of alternator charging, thanks to my slightly dodgy battery connections and the fact that I had other loads running off the alternator as well. The Charger 2 will automatically alter charge input according to the load on the alternator.
I only had a 200W solar panel, and I was testing the system in the late afternoon. Not ideal for maxing the panel. Still, I managed to get around 110W of solar. This resulted in a combined 750W, which is a pretty good result.
I will be sorting out my connections and trying a larger solar panel later down the track.
A WORD OF CAUTION
Prospective owners of the Charger 2 should consider their existing DC power usage and the loads they could potentially be placing on their alternators.
The Charger 2 can produce a load of around 60A if it is running at its maximum output, and that is a big load for many small vehicles. Further, you may have a dual battery system, driving lights, fridge and other high-power loads already on your tow vehicle. If that wasn’ t enough, if you tow a caravan, you’ re likely charging the house battery from your tow vehicle as well. All these loads will add up and could potentially put too much load on your car’ s charging system. You want to avoid that as much as possible.
