I posted this info in another thread but it was on the end of a long thread - so may well be missed by many. Reposting the info here so others get to see this info. I believe this small Hatz diesel genset to be very different to every other small genset I have seen...

Given the latest data suggests that charging up to 3.4v max can result in more cycles from the batteries (life span) is it feasible to use 17 3.2v cells in series for a 48vnom setup using a Victron Inverter ? Victron can accept up to 66v. 17 x 3.4v = 57.8v, 18 x 3.4v = 61.2v. If we charge up to...

Have read read many posts here re paralleling cells. Not seen anything really in depth about it though. I get that a group of cells that are paralleled all have the same voltage and that you lose visibility on each individual cell. What I am trying to figure out is what is the practical limit...

I am new to mppt's - never used one before so coming to terms with how they work. The inverter I am looking at gives these spec's; The panels I am interested give these spec's; and the **COLDEST** temps at my location (I am in a hot location but it gets a bit chilly at night - 62F/16C -...

I am trying to figure out how to charge a battery bank in the bow of a sail boat. The charge sources are at the stern of the boat (as I guess most charging sources would be in a sail boat). The battery bank up front would be around 30-40kWh at 48vnom. The DC cabling should support up to 200...

Just been hit with a dilemma. Was set to go with LiFePO4 system but have found that the country I am in, has this year (2022) introduced a 10% duty rate and 16% VAT rate on Lithium batteries. Lead acid batteries are duty free and zero rated for VAT (meaning no VAT is charged on them). I was...
