Heliotrope's HPV-22B

MPPT Solar Charge Controller for RVs

with Current Boosting Technology

The HPV-22B charge controller will deliver more charging amperage to your batteries (like the Solar Boost type controllers) and add in the proven, all important Tapering charge strategy. This will actually get you to full charge faster and friendlier than the older "ON/OFF" controllers do.

By pulling the included 25' temperature sensor cable from the controller to the battery , you can also utilize Battery Temperature Compensation which will adjust the finish charge set point up or down depending on your batteries' temperature. This prevents plate sulfation when your batteries are cold. When they are hot, it prevents unnecessary "boiling" of the electrolyte which drives water out of your batteries. Others make this important feature an "option" and charge you extra for their temperature compensation sensors. Ours comes standard with the controller and is included in our price!

The HPV-22B has the following standard features:

22 Amp Charging Capabilities
(Regulates up to 400 watts of solar input)


Current Limit On Output
(Eliminates nuisance fuse blowing)


Selectable Charge Set Point
(via a potentiometer on the circit board)


Tapering Charge
(Tapers off the charging amperage after reaching the set point for a full, gentle finish charge)


Battery Temperature Compensation
(Automatically adjusts charge set point with respect to battery temperature to help prevent excess water loss in warmer temperatures and/or plate sulfation build-up in cooler temperatrures)


Liquid Crystal Display
(Gives Digital readout of battery voltage, array input amperage, and boosted charging amperage)


Light Emitting Diodes
(Gives "at-a-glance" system status: "Charging", "Charged", and "MPPT" active)


An "On / Off" Switch
(This allows you to easily disable the controller when necessary without having to go out and pull a fuse at the battery. There are times when it is appropriate to turn off your solar charging system. One being if you are going to store your RV under cover or in a garage. If there is no sun available, then your controller will draw the power it needs to operate its logic and meter readout from your batteries which will slowly draw them down while in storage. Simply turning off the controller will resolve this issue.)


A "Dry Camp" / "Shore Power" Selector Switch
(When dry camping, you need all the solar power you can get. So, when this switch is set to "Dry Camp", the controller's charge set point is 14.3 to 14.4 volts. When you are plugged into shore power and have your inverter/charger or converter charging your batteries, you don't want your batteries to be held at that high of a voltage. So, when this switch is set to "Shore Power, the controller's charge set point is lowered to 13.2 volts. It will in essence be in a standby mode ready to spring into action should the shore power drop out.)
