Deep cycle battery system in the main house
The main house has a 24 Volt [V] battery system with a capacity of 420 Ampere-hours [Ah]. The battery system consists of four deep cycle batteries of the type 12 FS 210 by Rolls Battery. Each individual battery has an output voltage of 12 V and a capacity of 210 Ah at a discharging rate of 20 hours (please check datasheets for lower discharging rates). The four batteries are parallel- and series-connected, which doubles the system’s voltage and capacity.
As with all deep cycle batteries, they shouldn’t be drained to less than 20% of their capacity, which results in a usable capacity of 336 Ah with 24 V (~8,000 Watt-hours [Wh]) after purchase. If the hour rate (time to discharge the battery) is closer to 10 hours, the usable capacity fluctuates around 296 Ah with 24 V (~7,100 Wh). Please note that these numbers will be lower after long-term usage.
