At times of grid failure, with the flick of a change over switch located at the point your electricity supply comes into your property, you will be able to keep your essential loads running. Most central heating systems require a very small amount of power (50-80W), which means you’ll be able to keep your home energy system powered in a blackout for over 12 hours on our most basic system. Add further batteries to extend the longevity & off-grid capabilities of the system if needed.
Small loads such as lights, internet, TV’s, phones, and other health critical systems can be powered for a meaningful period of time. Cookers/Kettles and other high powered devices are not recommended for use from our entry level systems as they consume too much power and are considered non essential loads. Critically, being able to keep fridges, freezers and other devices on, can be very important depending on the circumstances.
At times of grid failure follow the following procedure to initiate the device
- Turn off the battery charger
- Activate the system using the DC isolator
- Turn off all non essential loads on your consumer board
- Initiate the change over switch.
Check your Victron Connect App to verify the system is powering your loads and consuming energy
Once the grid has returned
- Initiate the change over switch back to grid/mains
- Re-activate any of your non essential loads on your consumer board
- Deactivate the system using the DC isolator
- Re-activate the battery charger to re-energise the system for future outages.
Using the Victron Connect App verify your battery charger is in Bulk mode and recharging your batteries.
The system is adaptable should you wish to expand it in the future, and portable so you can move it around with you from properties or locations. At a fraction of the price of a full-blown backup solar battery system, it’s a good way of protecting yourself this winter. It allows for complete customisation and configuration, whereas an ‘all in 1’ battery system does not, or provide an easy way for maintenance, or upgrade.
Kettles, oven’s (+2000 watt) and other high consumption items will not run on the entry level systems, and should you require a higher wattage inverter, we can of course quote you for this by contacting us on email@example.com. The additional cost will be reflected in the higher capacity inverter, battery, and cabling to suit.
An electrician should charge for up to ½ a day, to install the changeover switch between £150-£250. It is not a complex installation, but will require your property to be without power during the connection for a very short period (15-20 mins).
We recommend finding a local electrician to keep your costs down and maintain flexibly, however if you’d like us to come and install the system and you are within 1h of London we will be pleased to do so for a similar fee.
You will need a footprint of 540mmWx375Dx360H to allow enough space for the system. It should be installed in a well-ventilated area, to ensure the inverter is able to operate effectively. The system should be installed in proximity to your consumer board. The change over switch must be installed at the same location of your consumer board, and you may use a long AC extension cable to locate the box elsewhere if necessary.
If you are renting you may need to seek prior authorisation from your landlord/freeholder. If you own your property no additional permissions are required, so long as a qualified electrician installs the switch.
