Solar Panel Charge Controllers. The Heart of your Solar Panel System.

Solar Panel Charge Controllers: the heart of any solar panel system.

To protect your batteries from overcharging and to get the best from your solar panels, you need a high performance solar panel charge controller. All SunWorks solar panel charge controllers are built using the best components and are highly reliable. All our controllers use efficient SunWorks PWM or DuoPWM technology to optimise solar charge and prolong battery life. We have been designing and building solar charge controllers since 1991, initially to withstand the rugged conditions of the North Sea.

SunWorks SB1Z solar panel charge controller

At SunWorks we believe that a well designed solar panel charge controller should:

  • Prevent overcharging of the batteries
  • Maximise the charge in the batteries
  • Prolong battery life
  • Operate completely automatically
  • Have a long and reliable working life

Our most popular Solar Charge Controllers:

The SB0 and SB1Z are low-cost, high performance charge controllers. Designed for solar panels of up to 11 Amps (170 Watts), these small, easy to use controllers will sit happily next to your battery and protect it from overcharging, whilst optimising the battery charge.

SunWorks SB1C and SB2C solar panel charge controllers

Our best-selling solar charge controllers, the SunWorks SB1C  and SB2C will control your solar panel,  optimise and protect your battery, and look smart in your living space. They are available in black or in light grey to suit the interior of your motorhome or boat.

Cables enter from the back or side of the controller.

SunWorks highly efficient precision charge technology ensures optimal battery charging.

The SB1C controller is suitable for solar panels of up to 11 amps (170 Watts).

The more capable  SB2C controller can handle solar panel arrays of up to 15 amps (240 watts).

The clear LCD display shows solar current and battery voltage level and all cables enter from the back so there is no unsightly wiring.

Dual Battery Controllers:

SunWorks DB1C and DB2C Dual battery solar panel charge controllers

The SunWorks DB1C was the World’s first dual battery charge controller. Designed initially to charge both the engine battery and the leisure battery of a sailing yacht, this controller has been carefully refined  to suit both motorhomes and boats. With this controller you can charge both batteries from a single solar panel. It is available in a choice of colours, has a clear LCD display and uses the SunWorks precision Duo charging system. This controller has proven to be the favourite among boats owners and motorhome owners alike.

SunWorks’ unique Winter Mode ensures that both batteries are looked after when your vehicle or boat is not in regular use.

Suitable for solar panels of up to 11 amps (170 Watts).

For larger solar panels the SunWorks DB2C controller is the answer. It has all the facilities of the DB1C, including Winter Mode, and can handle solar panel arrays of up to 15 amps (240 watts).

Rear or side cable entry is available on both models.

Z-Series Solar Charge Controllers:
