CH201

The CH201 is a microcontroller-based smart charge controller that is ideal for charging 12 Vdc VRLA batteries. The charger uses MPPT (maximum power point tracking) technology to safely manage amperage and voltage for optimal battery charging and longevity. It has dual inputs for use with a solar panel and/or any 15 to 50 Vdc charging source. The dual inputs provide the option for fail-safe charging. The CH201 also outputs various parameters to allow close monitoring of the battery and power usage via RS-232 or SDI-12.

In your system, use the CH201 to charge your battery and supply power to your peripherals and data logger. The 12 V output is regulated and switched, with the ability to charge a 12 V battery at a rate of 10 A.

Note: This charge controller is not suitable for lithium batteries.

The CH201 provides 10 A of charge current, making it ideal for systems with short periods of sun, or higher-current draw systems that require higher recharge rates. The CH201 has two input terminals that enable fail safe charging should one source drop out. It also incorporates an MPPT (maximum power point tracking) algorithm to maximize available solar. The CH201 has a programmable, low-voltage disconnect to help protect the battery. RS-232 and SDI-12 terminals allow the CH201 to be configured and to convey charging parameters to a data logger.

Compared to the CH200, the CH201 offers faster charging with the use of larger solar panels, up to 160 W. (Larger solar panels can be connected; however, when the system is running at full power, not all the current will be used.)

Compared to the SunSaver SS-10-12V, the CH201 offers:

• Dual inputs
• Current monitoring via RS-232 and SDI-12
• Configurability
• Low-voltage disconnect (The SunSaver SS-10-12VL has LVD.)
• Low current drain
