The product is ideal for heating systems or any other appliance under 300W in the event of a power failure. Thanks to this, in the event of an unexpected power cut, there is no need to worry about the heating stopping or a boiler overheating. The device automatically detects a power failure and switches to battery mode, recharging the battery when the power returns. 

So this device is, in effect, a freely configurable uninterruptible power supply consisting of an inverter and a built-in battery charger. Only one battery (AGM) of the desired size needs to be connected to the device. The capacity (size) of the battery must be selected according to the desired battery life (battery run time). Our expert colleagues can help you with the selection, but you can also easily calculate the size of the battery you need using the calculator below.
