Wakespeed WS500 Alternator Regulators & Accessories

Maximise the charging efficiency of your marine, RV, or off-grid 4WD power system with our comprehensive range of Wakespeed components. The Wakespeed WS500 is recognised as one of the most advanced alternator regulators on the market, specifically designed to protect your high-output alternator while delivering optimal charge profiles for modern battery chemistries, including lithium (LiFePO4). By actively monitoring battery voltage, current, and temperature, Wakespeed systems ensure your off-grid electrical setup operates safely and efficiently.

Advanced Alternator Control for Lithium Batteries

Upgrading to a high-capacity lithium battery bank often reveals the limitations of standard factory alternators. Without intelligent regulation, alternators can quickly overheat and fail when tasked with delivering continuous high currents to a deeply discharged lithium bank. The lithium compatible alternator regulators from Wakespeed solve this problem by continuously monitoring alternator temperature and modulating output to prevent thermal damage.

With built-in CANBus connectivity, the WS500 communicates directly with your Battery Management System (BMS) and other network devices, such as Victron Energy systems, ensuring charge rates are perfectly synchronised with your battery’s exact requirements.

Compatibility Notes

Correctly configuring your Wakespeed WS500 requires matching the regulator and harness to your specific alternator and battery system. The WS500 is compatible with 12V, 24V, and 48V systems, automatically scaling its charge profiles based on your configuration. When selecting a wiring harness, you must confirm whether your alternator is P-type (positive switching) or N-type (negative switching) to ensure proper field control. For advanced setups communicating with a Victron Cerbo GX or BMS, ensure you select a harness equipped with CANBus leads and the appropriate crossover cables.
