Product Description

2500 Watt Modified Sine Solar Generator | SOLGEN 25M

 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 25M – 2500 W Modified Sine Solar Generator is our most inexpensive solution. Compact, powerful and affordable, the SOLGEN 25M will provide power for remote sites, apartments, small homes, cabins, and RV’s.

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

  • 2500 W Modified Sine Wave Inverter
  • One 1200 Wh (watt hour) sealed lead acid solar AGM Battery
  • One 100 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 100 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 Modified Sine Wave* inverter generates power that is very handy for a range of applications – charging smart phones, laptops and tablets. The SOLGEN 25M is not only suitable for emergency situations but also terrific for everyday use to power lights, charge batteries and electronics, run basic appliances and tools.

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 25M – 2500 W Modified Sine Solar Generator makes free, clean power – no fumes, no noise.

Modified sine wave inverters, such as in this unit, work well for some motors or resistive loads (i.e light bulbs) but, are not recommended for sensitive electronics, audio equipment, or devices with microprocessors.  Transformer-less capacitive input powered devices or high intensity discharge lamps (e.i. metal halide) may suffer damage.  (For sensitive equipment, see our 2500W Pure Sine Wave Generator.)
