Good unit but not for lithium and has a issue with voltage accuracy

katey jane andrews on Nov 23rd 2022

Bought for the 50 amp dc-dc charger when I had AGM batteries. Overall the unit works well but when testing the voltage read out against a voltage meter it reads higher when in MPPT or when using the alternator, but when there is no charging the monitor is more accurate! I've treated the BVS cable and direct from the charger but the voltage reading is the same, so I am not sure if it sthis monitor or the charger hats misreading the voltage. I do not recommend the monitor screen for lithium batteries due to how the batteries maintain their high voltage so is much harder to gauge the SOC of the battery, Go for the shunt instead which gives you % of charging and discharging plus a whole load of useful features. This unit will be going in my motorhomes cab so i can monitor the system whole driving and will be using the shunt inside the motorhome.

Recently installed the 30amp DC to DC with MPPTcharger into my humble campervan..I’m impressed. Still got to figure out how this useful gadget works, once filled with the correct info this will prove invaluable.. everyday is a learning day. Well made compact and quick to instal..just needs brains.
