ExactlySun Boost / Step-Up MPPT solar controller

The unique GVB-8 boost charge controller with MPPT tracker is a real problem solver.
It makes it possible to charge batteries with a higher voltage using a solar panel with a lower voltage.

Would you like to charge a 24 V battery with a 36 cell solar panel (12 V nominal voltage)? No problem.

A 48 V battery with a 60 cell panel (20 V nominal voltage)? That's no problem either.

With a peak efficiency of 99 % and the ability to charge from an input voltage as low as 5 V,
they are the most efficient voltage boost regulators in the industry.

- Integrated fuse
- 99 % peak efficiency
- Ultra-fast true MPP tracking
- Excellent low light performance
- Compact for easy installation
- Available for lithium batteries

* Panel specifications have increased since the development of the GVB-8. Although we do not believe in changing specifications without appropriate technical analysis and adjustments, based on our customers' long experience and the power reserves built into the GVB-8 by the manufacturer, we recommend the GVB-8 for panels with an impedance of up to 9A.

Also available on request in a waterproof version, for lead batteries or other charging voltages.
