Two-step constant voltage charging and temperature compensation to optimize battery charging and increase battery life

Reverse battery protection

Programmable LVD (low-voltage disconnect) to protect batteries

DevConfig user interface to change system parameters or install a new OS

Two 15 to 50 Vdc inputs to accommodate multiple solar panels

Synchronous rectification in the switching regulator for increased DC/DC conversion efficiency

Individually programmable current limits on both of two inputs

Solid-state circuit breaker for automatic reset and more precise trip current

DC-to-DC converter with built-in output current control

Serial communication wiring through three terminals

Technical Description

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) algorithmto 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
