Heart Interface Freedom Inverter

[krabimike]

Good Day< just installed 4 - 6 volt deep clycle batteries 2 days ago. however when I charge with my Generator the 30 amp fuse for the inverter and charger keeps popping. when charge with the engine they charge fine. any thoughts as to what is causing the fuse to blow after charging for a short time?
thanks

Those are two completely different chargers - when you run the engine the alternator supplies the DC electric and the Heart Freedom is not involved at all.

Where is this 30A fuse? If it's between the Freedom's Positive battery cable and the battery, it is way too small for charging (or for inverting either). The Freedom can and will produce as much as 50A @14.4v when charging a large battery bank such as yours (which has 400+ AH of capacity). When inverting, the Freedom 10 can draw 90+ amps from the battery (depending on the wattage being produced)
