Heliotrope's HPV-30DR

MPPT Solar Charge Controller for RVs

with Current Boosting Technology

The HPV-30DR charge controller is the culmination of many years of Research and Development. Its feature set is the result of our experiences of living and working out of our RV and seeing what was and what wasn't working with other controllers. (see "Test Rigs") Its ease of installation comes from working with the "guys on the line" at our RV manufacturing accounts as well as from our own years of aftermarket installations.

There is so much automatically going on "under the hood" of the HPV-30DR protecting your RV and your Batteries that it is hard to describe it all in text. It is something that you will just have to experience. Let's just say that I seriously doubt that you will find any other solar charge controller that has all of the RV specific features that are built in to the HPV-30DR.

The HPV-30DR has the following standard features:

30 Amp Charging Capabilities
(Regulates up to 600 watts of solar input)


Charges both the House and Engine Battery Banks Simultaneously
(Up to 30 amps heads to the House Battery while up to 5 amps head to the Engine Battery!)


Proven 3-Stage Charging Method
('Bulk', 'Taper', 'Float' charging assures complete and gentle charging)


External Voltage Sensing (requires optional kit - see below)
(Measures actual battery voltage at the battery through an isolated pair of wires for the most accurate and quickest charging ... Other controllers measure battery voltage through their current carrying charging wires. That distorts the actual battery voltage the controller uses to terminate charging which causes the controller to taper off the charging too soon.)


Current Limit On Output
(Eliminates nuisance fuse blowing)


Voltage Limit On Output
(Eliminates Over Voltage shut down of Inverters and protects sensitive RV Electronics)


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 temperatures)


Selectable Charge Set Points
(via potentiometers on the circit board)


Light Emitting Diodes
(Gives "at-a-glance" system status: "Bulk", "Taper", and "Float")

The HPV-30 Solar Monitor has the following features:

System Mode Status LEDs
(This gives you "at-a-glance" confirmation of which charging mode the HPV-30DR is operating in by seeing which LED is lit. If there are no LEDs lit, then the system is Off.)

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 Three Position Selector Switch
(This switch dictates what shows in the Liquid Crystal Display. You can easily monitor the current House Battery Voltage, Engine Battery Voltage, or Solar Charging Amperage )


A Momentary Button Switch
(To the right of the Liquid Crystal Display is a momemtary switch. When you have the Three Position Selector Switch set to "Solar Charging Amps", you can press this momentary button switch and see what Amperage the Solar Array is sending to the HPV-30DR. When you compare the "Solar Array Amps" to the "Solar Charging Amps" you will see how much of a Boost in the Charging Amperage the HPV-30DR is delivering to your battery)
