Timeguard PV1000 Boostmaster White IP20 Solar PV Boost Immersion Controller Kit with Main Unit, Display Unit & Sender

Timeguard PV1000 Description

The Timeguard PV1000 Solar PV Boostmaster immersion controller transforms the excess electricity generated by your solar panels into free hot water, reducing the need to draw energy from the grid. Designed for use with existing solar PV systems and standard immersion heaters, this innovative controller continuously monitors exported power and automatically diverts surplus energy (above a set threshold) to heat your water tank.

Featuring a backlit LCD display and intuitive controls, the PV1000 provides real-time feedback on energy generation, consumption, diversion and savings — including daily, weekly and long-term kWh data. The system includes a main control unit, wireless display unit and sender clamp, enabling flexible installation and remote monitoring (up to about 30 m away). With programmable boost functions and adjustable activation thresholds, you can tailor performance to suit household usage and solar conditions.

Engineered to align solar energy generation with domestic needs, the PV1000 enhances self-consumption, reduces exported electricity (often sold at low tariff rates) and helps lower overall energy costs. Its robust design and comprehensive feature set make it ideal for homeowners looking for a practical, retrofit-friendly solution to maximise their solar investment.
