Why run dual alternators?

• The factory alternator does what it is designed for, recharging the factory battery and supporting the factory electrical needs.
• Dedicated charging system for your separate electrical system
• Compatibility with smart regulators to monitor and protect the alternator and batteries.
• Professionally engineered bracketry to adapt to modern engines
• High charge at idle
• Faster recharge of batteries saving time and fuel
• Generator replacement- using your existing engine with a Nations Alternator gives you unlimited power without adding any additional fuel or engine
• Reliability- Nations has the experience and quality to last under the harshest conditions

Wakespeed WS500 Advanced Regulator

• Active regulation of voltage, current, and temperatures to assure proper battery charging while protecting the system - including ensuring battery C rate is never exceeded without needing to artificially restrict the alternator capacity.

• Zero Output Technology allows alternators to continue to power house loads after the battery is fully changed.
• Adaptive Idle Technology reduces alternator load at lower engine RPMs to minimize impact on performance.
• Auto-adjusts for 12, 24, 48/51 volt systems and allows advanced user-configuration for system voltages in between.
• CAN communication for ease of install and reliable measurement of critical battery and system information such as: battery amperage/voltage, alternator and battery temperature, battery capacity and status, electrical and engine loads
• Full BMS and Operator Display compatibility using RV-C, OSEnergy and other protocols
