Solarstone PV systems can be successfully implemented as a hybrid and grid-free off-grid power plant in addition to conventional on-grid solutions. We use Victron inverters and BYD battery solutions, which can be combined with a generator system if necessary, operating independently of the mains connection and ensuring almost complete autonomy.

We offer 4 different approaches to building offgrid systems. The prices below do not include equipment installation work.
