Hi All,
After looking through the literature for the 12v Victron Multiplus II 3000VA, it states a minimum requirement of 400Ah battery capacity.
This system is a bit overkill for my present needs (small shed/cabin home office) but I purchased it to allow for future additions/upgrades.
The max load I’ll be drawing at any time will be well below the capability of the unit (likely no more than 150w on average with around 1400w peak/surge when including the momentary startup load of a small fridge/freezer unit), I had intended to use 3x 100Ah Victron high current superpacks with the following specs:
Nominal Capacity – 100Ah
Charging Current – 50Amp
Max Charging Current – 100Amp
Max Discharging Current – 200Amp
Max Continuous Current – 100Amp
Max Charging Voltage – 14.0 ~ 14.6V
3 of these batteries would be under Victrons recommended Ah capacity but wouldn’t the loads be comfortably within the limits for the continuous discharge current for 3 of these batteries, especially considering the max discharge rating of 200A per battery?
In truth at one point I was wondering whether I could get away with using just 2 of them?
Should this be OK or if not, what else do I need to take into account?
The rest of the system comprises 3x200w panels, a 100/50 Charge controller, 12/3000 Multiplus II Inverter, lynx distibutor and shunt and a Cerbo GX.
Many thanks.
