MyReserve was developed for quick plug & play installation, and the low weight means that qualified technicians can easily carry out installation without a second person.

A great retrofit solution for almost any PV system and suitable for all sorts of system sizes. Simply fits between the PV array and solar inverter.

  • Extremely low self consumption (5W in standby mode, 5-15W in operation) to maximise use of solar energy.
  • World leading battery efficiency of 99.2% and 93% full cycle efficiency.
  • Very fast response time to match varying loads and generation to ensure highest possible self consumption of solar generation.
  • Low heat losses so no battery cooling required.
  • Superior battery design and construction for overall safety and to eliminate fire risk.
