Solar Charge Regulator Steca PR
The Steca PR 10-30 series of charge controllers is the highlight in the range.
Use of the latest charging technologies combined with state of charge determination enable optimal battery maintenance and module power monitoring for up to 900 Wp of connected power. A large display informs the user about all operating modes with the aid of symbols. The state of charge is represented visually in the form of a tank display. Data such as voltage, current and state of charge can also be displayed digitally as figures on the display

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.
