The Instapark MPPT series solar charge controllers are designed and engineered to prevent your solar-powered battery from overcharging and excessive discharging, therefore protect your investment and extend the battery life. Equipped with MPPT (Maximum Power Point Tracking) technology, this 20 amp charge controller ensures that your battery will reach its maximum charging capacity by sampling the output of the cells and applying a resistance (load) to optimize the ideal voltage and current conditions, therefore maximize the power gain from the solar panel for any given environmental conditions, resulting in highest charging efficiency, fastest recharging and a healthy battery at its fullest capacity.

All MPPT series solar charge controllers are in full conformance with both CE and RoHS standards and are backed up by a standard 2-year manufacturer's warranty.

5Fantastic price for MPPTOct 20, 2013
This controller is made by Steca. German designed.
Lowest price out there for a real MPPT controller.
Morningstar units are $275.

Amazon is one of the only sellers of this item in the US.

Buy this before they vanish!

01/29/2014 Edit

There is slight extra plastic flashing over the hookup point screw holes.
It's very thin and can be poked out with a screwdriver or toothpick.
It makes it appear that there was a manufacturing defect.

The controller is 20A @ 12v and 10A @ 24v. Stated clearly on the box.

5Over One Year Of UseMar 01, 2014
By Amazon Customer "SEO/SEM"
So I waited to write a review and I don't have many here on Amazon. I have this controller attached to the outside of a very large Stanley 24-Gal. Mobile Chest Tool Box. Inside I have 4 - 6 volt deep Cycle Golf Cart Batteries wired in series and parallel for a total of 12 v and a total 428 amp hrs. Inside the box above the batteries in a tool slider box is a Tiger 1500 watt inverter. All this connected to (2) Renogy 100 watt solar panels. The Stanley tool box although has it two wheels on the back has been placed inside a metal wagon garden cart.

This entire unit is then loaded onto my utility trailer that hooks to my Jeep and goes on any off road I want.

Which Brings me to the actual review of this unit. It has held up under extreme heat, cold rain and snow. Extreme dust and dirt. Roads that would shake the daylights out of most electronics after only one time, let alone multiple trips to my off grid property.

This unit is outstanding in my book.

5Great performanceApr 23, 2014
By John
I read the previous reviews, and decided to take a chance; yes you have to punch out a little plastic flashing, but it comes out easily. This charge controller is worlds better than my previous PWM Controller. I am running 3 100 watt monocrystalline Renogy panels in series pushing 66 volts on average and three 12 volt Exide Deep Cycle Batteries in parallel. I can add one more panel, if you go over 100 volts it will fry this controller. The system is usually fully recharged by 11am. We run our living room off this modest system, a 46 inch LCD TV and surround sound system and CFL 9 and 13 watt lamps. I will be adding more as we go, but this is a solid reliable setup. It feels like I have 4 panels on the roof.

1Manufacturing defect makes unit unusable without modification. Documentation does not match posted specifications.Dec 30, 2013
By Stewie
I was really looking forward to using this to swap out a PWM controller but when I got around to attaching the wiring, I discovered problems. If you look at the product photo for this or any similar charge controller, there are 6 access holes/locations at the bottom of the front of the unit that expose the screw down terminal blocks for wiring it up:

Panel +/- Battery +/- Load +/-

Unfortunately the one I received only has 4 holes, the two that should be in the center for accessing the Battery +/- screw down terminals are missing. The terminals themselves are present beneath the plastic, there's just no way to access them like the other 4. No knockouts or anything similar are there to use, it's just solid plastic. This is an obvious manufacturing defect in the cover, and I could probably drill my own holes and/or take it apart, but this never could have passed QA/QC as it is untestable as-is.

Additionally, the Amazon product description (and the vendor's website) claim this is a 20A controller for both input and load:

Max. solar panel current: 20 amp @ 122°F
Max. load current: 20 amp @ 122°F

The documentation that comes with this controller on page 8 (technical specs) states that the maximum load current is only 10 amps. The product literature for The Steca Solarix MPPT 2010 also shows it as having a 10 amp max load:


To sell this as a 20A controller is a bit misleading at least. But posting the wrong specs in two places?

Maybe the price is so good for this controller because they were purchased from Steca as refurbished, obsolete stock, or as cosmetically defective re-brandable units. A Steca MPPT 2010 controller costs 3 times as much as this, that makes me suspect the real possibility of it being a knockoff.

Returned for refund.
