Many consumers who are charging batteries with solar panels or have a grid tied system with battery backup will need a charge controller. A charge controller is a unit that sits between a solar panel and battery bank and regulates the charge so the battery is not over-charged.

Blue Sky Energy, Inc. is a quality driven, customer oriented company. Our development of Maximum Power Point Tracking technology in 1998 led to the issuance of two patents. Our products are used worldwide to provide power in battery based or off-grid systems. Whether the system is a remote telecomm site, security camera, portable solar power system for the military, an RV or boat, Solar Boost products are selected because of their proven reliability, consistent quality and affordable prices. Our patented technology delivers up to 30% more power from your PV Modules than conventional solar charge controllers.

Blue Sky Energy SB2000E

SB2000E

Increase your solar panel output up to 30% with this new photovoltaic charge controller. Patent pending technology gives this charge controller the capability to use all the power your panels are capable of putting out. You could actually consider using less panels! When your batteries are low and you have sun, you will get maximum power out of your panels. Under boost conditions it is like having an extra solar panel, but without the cost and the extra weight.

The SB2000E comes with LCD display and is flush mounted (RV style). Optional conduit box for surface mounting is available.
