Electrical and energy calculations are not final designs by themselves. Load profile, conductor conditions, protection, efficiency and local codes must be considered together. Sorsana tools are intended for preliminary sizing and scenario comparison.
- Continuous and surge characteristics of the real load
- Cable length, conductor material and ambient temperature
- Battery, charger and inverter efficiency plus usable capacity
- Manufacturer data and applicable local electrical codes
