The supplied XT60-to-car adapter cable can prove helpful on the road, for example in the car or camper. However, with a maximum charging power of around 120 watts, it takes quite a while to charge a significant amount of energy into the storage unit.
It can be faster with connected PV modules. Oukitel speaks of a maximum of 1,000 watts, which can be fed in via the XT60-to-MC4 adapter that is also included in the scope of delivery. To achieve this high charging power, several PV modules would have to be connected in series. Oukitel’s own portable solar module delivers 400 Wp, which is roughly equivalent to the power that conventional current PV modules can deliver.
As the BP2000 can be charged simultaneously via the mains connection (AC) and DC input, the maximum charging power is 2,800 watts, at least in theory. In practice, one or the other option will probably be used in most cases.
The B2000 expansion battery can also be charged – in solo mode – via an XT60 port using connected PV modules, although the charging power is limited to 200 watts.
