Product Description

1500 Watt Lithium Powered Solar Generator

Compact. Powerful. Affordable.  Clean power at your fingertips.


Power When You Need It – whether preparing for a grid down situation or just looking for an inexpensive way to generate clean power, the SOLGEN 15L – 1500 Watt Lithium Powered Solar Generator is a great solution. Compact, powerful and affordable, the SOLGEN 15L provides utility quality power for remote sites, apartments, small homes, cabins, and RV’s.

This expandable system uses a 100-, 200- or 300-Ah battery (providing the same power as up to six sealed lead acid batteries) and up to four 150 watt solar panels.   This generator uses a 30 amp Constant Current / Constant Voltage (CC/CV) charge controller which allows system growth and is our most compact and POWERFUL Portable Pure Sine Wave Lithium system.

The 1500 Watt Lithium Powered Solar Generator  INCLUDES everything you need to start making and storing power by simply connecting the solar panels and pointing them at the sun – power can be used from the system while it is being charged by the sun. The 1500-watt Pure Sine Wave* inverter generates power that is just like the power that comes out of any home outlet. It is very handy for a range of applications – charging smart phones, laptops and tablets. The SOLGEN 15L is not only suitable for emergency situations but also terrific for everyday use to power appliances, computer equipment, lights and your favorite entertainment devices.

When you choose to power tools and/or appliances with a solar generator, you’re making a positive impact on the environment by reducing carbon dioxide emissions that destroy our ecosystems. Fuel-powered generators can’t compete with that. This 1500 Watt Lithium Powered Solar Generator  makes free, clean power – no fumes, no noise.

Pure sine wave inverters, such as in this unit, have very low harmonic distortion.  They will run your equipment more efficiently and quietly and, will reduce wear on motors.  It is best to use pure sine wave inverter systems for sensitive electronics, audio equipment, devices or appliances with microprocessors, CPAP machines and other medical equipment.
