The Cutting Edge Power FORTRESS is ready to protect your equipment with its waterproof and vandal-resistant design!  Perfect for permanent installations like trailers, boats, boat docks, etc. 

Featuring a plug and play concept, the Fortress solar generator can be purchased with a battery, or you can use your own 12V battery.  With inverter options up to 5000W, this solar generator can provide some serious power.  All connections are made inside the box.  Cable entry/exit can be made through dedicated cutouts on all four sides so NO DRILLING IS REQUIRED.  Professionally wired in Houston, TX, all you need to do is connect the 5/16" battery ring terminals.

As with all waterproof electronic designs, heat can become an issue - Especially with a black box in the sun!  But Cutting Edge Power has you covered with a temperature-controlled fan that will cool off the internal components without draining the battery.

This device can also be used with 4S 12.8V lithium iron phosphate LiFePO4 batteries.
