Product Description

2500 Watt Pure Sine Solar Generator | SOLGEN 25P

Compact. Powerful. Affordable.  Best for Sensitive Electronics.


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 25P – 2500 Watt Pure Sine Solar Generator is a great solution. Compact, powerful and affordable, the SOLGEN 25P provides utility quality power for remote sites, apartments, small homes, cabins, and RV’s.

This expandable system uses up to three AGM Deep Cycle 100 Ah batteries and three 150 watt solar panels. Start small with one battery and one panel and add on as your need requires and your budget allows. This generator uses a 30 amp PWM charge controller which allows system growth and is our most affordable Pure Sine Wave system.

This 2500 W Pure Sine Solar Generator comes with the following:

  • 2500 W Pure Sine Wave Inverter
  • One 1200 Wh (watt hour) sealed lead acid solar AGM Battery
  • One 150 W Solar Panel
  • 30 amp PWM Charge Controller
  • 120 V Duplex Outlet
  • External Power Access Panel – for charging phones, tablets, laptops or just providing power through the circular 12 V supply (cigarette lighter style) for lights and other appliances. Panel also includes a digital voltmeter for easy monitoring of battery voltage.
  • Proprietary Battery Maintenance System – keeping batteries charged when not in use is the key to maximum longevity and protection of your battery storage investment. Our built-in maintenance systems will ensure that your batteries last longer than anything else on the market.  Requires AC power.
  • 250 amp ANL Fuse
  • Heavy Duty Battery Cables
  • 30 ft Solar Wire – connect solar panels to the batteries
  • Expand to three AGM Batteries and three 150 watt Solar Panels. 

Start small with one battery and one panel and add on as your need requires and your budget allows.

SYSTEM INCLUDES everything you need to start making and storing power by simply connecting the batteries and pointing the panels at the sun – power can be used from the system while it is being charged by the sun. The 2500-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 25P 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. The SOLGEN 25P 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.
