The Model ST 4000-60 TSW
Sun Tracking Portable Solar Power System…. Powerful, Portable, Fully Automatic and Affordable.
As of December 1st, 2019, we now offer Lithium Valley lithium-iron phosphate batteries as an option on our Models 5000, 6000, and all the ST Series.
Little Brother to our flagship ST 6000-100!
For those who don’t have the need or room for the ST-6000 and it’s capabilities. Features 1260 watts of built-in solar panels that can be raised and adjusted at the push of a button! This is currently the smaller of our ST Series, but shares many features of it’s larger relative, including an identical command-and-control system, which is made right here in Maine in our own electronics shop! All these larger units come standard with 240 volt AC output to run many deep-well pumps (or most anything else)!

1Since LiFePO4 batteries can be safely drawn down more than 95% vs. 50% for lead/acid batteries, the lithium battery option almost doubles the usable power from the battery bank vs. the stock lead/acid AGM batteries. Combine that with the lithium batteries lifespan of 3000 to 5000 deep-discharge cycles vs. 300 to 500 for even the best lead-acid batteries, and the slight added cost for the lithium batteries makes a lot of sense.
