How can I configure bolt to work with solar?

Solar Options

Bolt e-boiler and solar panel

Here at bolt, sustainable energy is very important, so, as part of our customisable packages, solar panels can be added to the install. Bolt can be interfaced with its own dedicated panels to form a PV storage system at a fraction of the price as no grid tie inverter is required, making green energy financially viable for everyone.

If you already have a solar and battery system installed, bolt can utilize these to effectively boost your home energy storage. If you don’t, bolt can still use tariff tracking to charge your battery off the grid with off-peak, low-cost electricity.

Flexible and future proof

Remote monitoring for smart home system integrations
