## Description

Stationary batteries for solar or wind energy banks; call us on +34 951 870 157 before you buy.

Storing what solar panels or a wind turbine produce calls for a battery that cycles every day and seldom reaches 100 %. This category gathers stationary batteries for **renewable energy storage**, such as the PowerSafe SBS XC+ series, built on **thin plate pure lead (TPPL)** AGM technology.
Compare capacity, voltage and cycling behaviour before you decide.

## A different job from UPS standby

In backup duty the battery is almost always full. In a renewable system the opposite happens: it charges when the sun shines or the wind blows, drains overnight and often spends days at half charge. That **partial state of charge (PSoC)** regime sulphates conventional batteries quickly. Thin plate pure lead blocks accept high charge currents and refill faster, which pays off when production hours are short.

## Sizing the battery bank

- **Energy**: multiply voltage by capacity. A 12 V 100 Ah block stores 1.2 kWh nominal.
- **Depth of discharge**: keeping it shallow extends cycle life; working at 50 % instead of 80 % multiplies the cycle count according to the maker's curves.
- **System voltage**: 12, 24 or 48 V depending on inverter power; more power means higher voltage and lower current per cable.
- **Days of autonomy**: how many days without production you want to cover.

## Setting up charge controller and inverter

Program the absorption and float voltages given on the battery datasheet into the controller rather than a generic profile. Enable temperature compensation if a sensor is available and avoid discharging below the recommended limit: a correctly set low-voltage cut-off protects the bank better than anything else.

## Renewable storage FAQ

### Can I extend the bank later?

It can be done, with limits: new and used batteries age at different rates. Sizing correctly from day one is the better approach.

### Lead or lithium for self-consumption?

Lithium offers more cycles and less weight but needs a battery management system that talks to the inverter. AGM lead is simpler to integrate and copes better with cold.

### Where should the batteries go?

Somewhere ventilated, dry and as thermally stable as possible, close to the inverter to keep cables short.
