How it works with a Solar system

When this Victron home battery storage system is set up to work with an existing solar installation, you would wire it into the mains and connect the blue CT clamp around the incoming supply. This CT detects the flow of power in and out of your property when there is excess solar the CT will detect this and allow the battery to charge. However, when there is no solar or little solar and power from the grid passes by the CT this will tell the battery to discharge and cover the load that the grid was supplying, this means that your bill will be reduced and your purchasing of electricity from the grid will be less

How this battery works with cheap rate electricity

If you don't have solar or even if you do have solar you can charge your battery from cheap overnight electricity using a smart meter or Economy7. This means that while you're asleep your battery system can come on automatically and charge from this cheap rate electricity and again turn off automatically, this is normally between 4 & 6 am. This would enable you to run your house on batteries for the remainder of the day depending on your usage.

Power during a powercut or blackout

Built into the Victron inverter charger is a secondary output which can be used in the event of a power cut to provide power from the batteries to keep your house powered with electricity to run things such as fridges freezers boilers and lights

Online monitoring

Built into the Victron is a GX device, this GX device will plug into your Internet connection or connect to Wi-Fi and allow you to monitor and control your system from anywhere in the world. This gx device is controllable from your mobile phone or laptop and allows you to make settings changes and to enable and disable charging schedules. It would also allow Callidus to come onto the system remotely and check that it's working correctly once you have set it up.

The kit needs to be installed by a competent person.
