Product Details

SunGuard Solar Regulator 4.5A

Solar charge controllers or regulators are recommend to avoid battery damage from overcharging or deep discharge. The Morningstar SunGuard regulator is designed for simplicity of installation and can be used with gel, AGM (absorbed glass matt), sealed and non-sealed lead acid batteries.The SunGuard uses an advanced series PWM (pulse width modulation) charge control for constant voltage charging. A true 0 to 100% PWM cycle is very fast and stable, ideal for efficient battery charging.,100% solid state design using MOSFETs rather than mechanical relays. The unit can be mounted inside or out as the cables covered in Hypalon insulation.

Solar Panels and Chargers

Solar “photovoltaic” panels use the power of the sun to generate electricity and can be used in a variety of applications from calculators to homes. They are most effective, versatile and cost saving in many commercial and leisure applications for charging 12/24V batteries.
Solar panels provide power through batteries at off grid and isolated locations and are widely used in critical telecommunications and telemetry applications. Solar panels enable rapid installation of equipment at remote sites, either temporary or permanent, avoiding the costs and inconvenience of grid connection. They are designed for very low maintenance and longevity.

How Much power?

The daily power production of a solar panel can be calculated by multiplying the panel’s peak power rating by between 0.5 and 6 depending on the time of year, angle and location. For example; an 80Watt solar panel produces a peak current of 4.55A.

Solar Installation

Solar panels are usually installed at a 55-65° angle for optimal wintertime performance. For a year round power supply solar panels can be combined with Wind chargers.
Solar panels can be connected in parallel to increase power and in series to increase voltage.
To complete the system deep cycle batteries, a voltage regulator and electrical cables are required to get up and running. A range of convenient mounting kits are available for pole or wall mounting.
