48 Volt DC | 4,000 Watt
When wind or solar power is not available, or you need to take batteries offline, this DC generator/alternator can be part of your power backup solution. It's paired with a Wakespeed WS500 advanced voltage / charge controller.
The WS500 is the only alternator regulator available that can utilize current, voltage and temperature to deliver the most precise and effective charging possible for 12V, 24V and 48V battery systems – with configurability for voltages in between – making it the perfect solution for charging lead acid based, or new generation LiFePo4 lithium ion battery banks.
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. In addition, 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 swiches. 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.
The WS500 can be used with different polarity alternators by selecting the appropriate N-Type or P-Type regulator wiring harness. Wiring harnesses are equipped with high-quality Ampseal connectors and provide all connections for basic operation, as well as dedicated connection wires for voltage and current sensing. See our Technical page for more information.
The Wakespeed® Offshore WS500 voltage regulator is built in the U.S.A. and features an industry-leading two-year limited warranty.
What size engine is needed to use this?
When you convert power from one form to another, there is always some loss in the process. Where does this power go? Part of the loss is in the way of heat from combustion and as heat from friction. An alternator or generator is only 80- 90% efficient. When deciding what size motor or engine will drive your alternator or generator, you should consider the loss in your calculations.
Horsepower is a unit of measurement of power.
1 HP is approximately equivalent to 746 watts, below.
This Alternator can produce up to 4,000 watts.
Before you begin...
- It is important that you find a safe and secure way to mount the alternator / generator and supporting components.
- Choose an appropriate size belt and pulley.
- This kit is for the DIY'er and will require some work.
Look for a soon to be released DC Generator from AURORA Generators using these very same components.
