Heliotrope PV manufactures solar charge controllers. These solar charge controllers are available in different models such as HPV-22, RV-30S, RV-45D, RV-30D, HPV-22B and HPV-30D. The HPV-22B solar charge controller consists of an on/off switch and a dry camp selector switch. In addition to above features, this solar charge controller also has a liquid crystal display, battery temperature compensation, light emitting diodes, current limit on output and selectable charge set point features. The on/off switch of the solar charge controller from Heliotrope PV is used for deactivating the controller.
HPV-22B Solar Charge Controllers
The HPV-22B solar charge controller has a dry camp selector switch and a shore power selector switch. The dry camp selector switch sets the charge set point of the controller as 14.3 volts to 14.4 volts, using a potentiometer. When the solar charge controller is plugged to shore power, the inverter/charger will charge the batteries. The selection of shore power selector switch sets the charge set point of the controller to 13.2 volts. The shore power selector switch will help to change into a standby mode if there is a shore power dropout.
The HPV-22B solar charge controller has a liquid crystal display unit that provides battery voltage, boosted charging amperage and array input amperage status.
