Choose from our two Pulse Width Modulation charge regulators. (The other is the HRSi regulator listed separately. Pleese see the related products tab). Both models progressively slow down the turbine when the batteries become full thus reducing long term wear and tear to the turbine. Note that voltage regulators should always be sited < 1.5m of the battery to minimise voltage losses, ensuring accuracy of regulation.
The HRDi Charge Controlleris the latest wind and solar regulator from Marlec.
The HRDi has evolved from and improved on the successful HRDX controller. It provides Charge Control and Power Splitting for off-grid system with two independent batteries, such as the cranking battery and leisure battery on a boat. The contemporary design meets the needs of increasing power demands and features a useful digital display that shows the amount of generated free power, along with the battery state of charge. It is designed for use with the Rutland 504, 914i or FM910-4 Windchargers and up to 160W of solar panels.
