                                Our Battery Recommendation

                                How We Recommend

                                Required nominal capacity = Daily energy consumption × Storage duration ÷ 90%. We prioritize the smallest single-battery capacity class that meets your needs, then select the lowest Cost / Wh within that class. If one battery is insufficient, we estimate a multi-battery solution, prioritizing fewer units and then lower Cost / Wh.

                                Cost / Wh = Listed battery price ÷ Nominal capacity in Wh. All estimates use the listed reference prices in EUR, excluding any additional system or installation costs.

                                Estimates are for initial planning only. Actual usable capacity depends on battery performance, inverter losses, temperature and system configuration. Multiple-battery recommendations require verification of parallel compatibility, maximum unit count and inverter suitability before purchasing.

Some 24V 80 lb motors draw up to 56A, and some 36V 112 lb motors draw 52A, exceeding these batteries' 50A continuous discharge ratings. Always confirm the exact motor voltage, maximum current and manufacturer requirements before purchasing.
