Phocos CXNup20-2B Solar Charge Controller, Negative Grounding, Two Battery Loader (12/24V)
Description
Phocos CXNup20-2B
PV solar charge controller - two battery loader
The CXNup series is a highly intelligent charge controller family for a wide range of applications. It features an intuitive user interface and stores up to two (2) years of valuable system performance data, which is accessible via the LCD and PhocosLink software. Real-time battery voltage, battery state-of-charge (SOC) in percent, charge and load current, and system status are clearly displayed on the large, backlit LCD. Optional acoustic battery alarms and a programmable street light settings are also standard. The CXNup2B offers the possibility to charge two independent batteries with up to 20 A. All other variants offer a USB port to charge mobile phones, tablets and other USB devices.
