BISOL off-grid systems

BISOL off-grid system allows people to simply stop worrying about electricity supplies whether they are cosy in their home or enjoying their well-deserved holidays on a boat or in a remote cottage. It serves as a back-up plan for the areas where power supply is often disrupted or where public electricity grid is unreliable, and even provides electrical power to the areas with no electricity grid.

  • MPPT Solar Charge Controller

A solar charger gathers energy from PV modules and stores it in the batteries. With the usage of the latest and fastest MPPT technology it maximises this energy harvesting and drives it intelligently to achieve full charge in the shortest possible time. A solar charge controller maintains battery health and extends its lifetime.

  • Pure Sine Wave Inverter

An inverter and charger combined in one elegant package (1) include a true sine wave inverter, adaptive charging, hybrid PowerAssist technology, plus multiple system integration features.

  • AGM Deep Cycle Solar Batteries

The design principle for the batteries is based on the usage of grid plates and ESS technology. The high energy density of the batteries results in a very low space requirement, thus enabling maximum utilisation of your premises.

  • Wiring and Other Electrical Material Set

All BISOL off-grid systems include the necessary solar cables, PV connectors and other wiring. Larger systems also include electrical cabinets with battery monitor, fuses and SPD.
