Off-Grid Battery Chargers
When battery charging options become limited due to equipment issues or outages, DC-Battery Charging Generators make an excellent choice for prime or emergency backup. AURORA DC Generators are portable, easy to use, and very cost-effective. Since they can be connected directly to batteries, they eliminate the need or limitation you may have with existing charge controllers and inverters.
AURORA DC-Generators are available with either gas or diesel engines, both with or without auto-start controllers. Auto-start controllers automate the generator operation much as they do with larger standby generators. They provide additional instrumentation and control with the ability to be started remotely using any standard two-wire starting system.
If paired with a Wakespeed WS500 advanced voltage/charge controller, precise and effective charging is possible for 12V, 24V, and 48V battery systems using LiFePo4 lithium-ion batteries, lead-acid or AGM.
Developed during years of cruising in the Pacific Northwest, the WS500 is uniquely designed to be configured via easy-to-use onboard DIP switches or can be connected to a PC to provide more than 100 user controls. The WS500 can also be connected to battery BMS modules other CAN J1939 devices through its data ports, making it the only regulator of choice to provide safe and smart charging for LiFeP04 and other emerging battery technologies.
The WS500 can be connected to a current shunt to monitor current flow to and from the batteries, enabling the regulator to control charging based on a combination of system voltage and amperage delivered from the alternator to the batteries. Also, the WS500 can also monitor alternator and battery temperatures and modify charging output to ensure optimal safety and charging performance at the alternator and batteries. When connected to a BMS system, the WS500 can receive critical voltage, current, and temperature data via the CAN J1939 pathway, reducing the need for external sensor connections.
The regulator’s auto-detect function identifies system voltage and automatically adjusts charging to support 12V, 24V, and 48V profiles. Default profiles for eight battery types can be configured at the regulator via the DIP switches. Selectable profiles include programs for standard and deep cycle flooded lead acid, standard and high-density AGM batteries, carbon foam AGM (Firefly), Gel, and LiFeP04. Two profiles allow for the flexibility to customize profiles with a PC, using the WS500 Configuration Tool or a terminal program like Putty. Support for non-common battery voltages (such as 32v) may also be configured in the same way.
