PowerSafe batteries

This section gathers PowerSafe batteries from the SBS XC+ series, built with thin plate pure lead AGM technology.

There are 2 V cells to form a bank at the voltage you need and a 12 V monobloc for compact installations. Compare capacity, dimensions and weight before you decide, so the bank fits both the load and the room.

Size your PowerSafe bank step by step

First, system voltage. Your inverter or rectifier sets whether you work at 12 V, 24 V or 48 V. With 2 V cells you need 6, 12 or 24 units in series respectively, all of the same model and capacity.

Second, capacity. Work out daily consumption in Wh, divide it by the bank voltage and add a margin so the bank is not drained deeply every day. For backup, the yardstick is the runtime the UPS or telecom equipment must cover during an outage.

Third, space. Check the length, width and height of each unit, the total weight on the rack and the ventilation of the room.

With these three figures in hand you can compare models side by side and see at a glance which cell gives the runtime you need in the space you have.

Typical applications

The SBS XC+ series works in off-grid and self-consumption solar systems, in UPS installations and in telecom equipment. For more about the brand and its technology, visit the PowerSafe brand page.

Frequently asked questions

What does TPPL offer over a standard AGM?

Thin pure-lead plates cope better with partial state of charge and frequent cycling, which is everyday life in a solar bank.

Can I extend an existing bank with new cells?

Mixing cells of different age in one string is a bad idea. To extend, add a complete parallel string or renew the whole bank.

Does it need maintenance?

There is no water to add. Simply check from time to time that connections are tight, terminals are clean and the charge voltage set on the inverter or rectifier matches the value recommended for sealed pure-lead batteries. Keeping the room at a moderate temperature also helps the bank last.
