Maximize solar generation by harnessing multiple PV sources

Dual Solar Input System with Independent MPPT Technology

Maximize the potential of solar energy by simultaneously utilizing multiple photovoltaic (PV) sources with our innovative dual solar input design, each with its independent Maximum Power Point Tracking (MPPT) technology. Enjoy a seamless integration of solar power into your home or business, whether you have multiple solar panels or a combination of rooftop and ground-mounted installations, making the most of every ray of sunshine. Voltage and current in real-time to give you optimum solar generation throughout the day, even during cold and cloudy days.


Solar generators don't burn fossil fuel, so with zero emissions or fumes, they're a clean, eco-friendly replacement for gas generators.


Without internal combustion engines, solar generators are extremely quiet. From a distance of approximately 20 inches, the noise level of a DELTA 2 Max solar generator (low input and output of around 500W) is only 30 dB, versus others with a volume of 45 dB or higher. In comparison, gas generators can run at an average of 70 dB, even from a distance.


Unlike gas generators, there's no fuel to refill, filters to clean, or moving parts to break. Without engine oil level checks, oil changes, or spark arrestor inspections, spend more time doing what you like.

Use Safety Indoors

Outdoors is the only safe place to operate a portable gas generator, keeping your family safe from toxic carbon monoxide. Since it doesn't emit any fumes, you can use a solar generator anywhere, inside or out.
