Storage is the critical point of every emergency power and solar system. Keyhan Energy supplies Industrial Battery matched to your application: UPS battery, Solar battery and batteries for telecom sites — with a charger matched to the battery chemistry.
Types of industrial batteries
- Sealed lead-acid battery (VRLA / AGM): The economical, proven option for UPS and emergency power; maintenance-free.
- Lithium battery (Li-ion / LiFePO4): Several times the cycle life, lower weight, faster charging; the choice for modern solar and telecom systems.
- Solar deep-cycle battery: Designed for daily deep discharge in off-grid systems.
Battery capacity selection guide
- Load power (W) and required backup time (minutes/hours)
- Allowable depth of discharge — sealed lead-acid ~50%, lithium up to ~80-90%
- Bank voltage (12/24/48 V) matched to the inverter or UPS
- Installation ambient temperature — battery life drops sharply as temperature rises (roughly halving with every 10-degree increase)
