Manufacturer: Morningstar Corp
Manufacturer Part#: PT-MPPT-25
The Prostar MPPT, solar charge controller with TrakStar Technology is advanced maximum power point tracking (MPPT) battery charger for off-grid photovoltaic (PV) systems up to 1100 watts. This controller allows multiple modules in series for 12V and 24V battery systems. Detailed battery programming options allow for advanced battery support for the latest Lithium, Nickle Cadmium, and Lead Acid battery types.
ProStar MPPT Solar Charge Controller
12/24V, 40A without Meter Display
The lastest addition to Morningstar's ProStar line of controllers is
here- and it's MPPT! This 40A MPPT Charge Controller is capable of
charging all battery types, including Lithium Ion.This is the first
mid-range MPPT controller fully UL and IEC listed, that has integrated
lighting and load control. The NEW ProStar MPPT™ is a mid-range MPPT
solar charge controller with TrakStar Technology™ that provides maximum
power point tracking (MPPT) battery charging for off-grid photovoltaic
(PV) systems up to 1100 watts. This device is ideal for industrial and
residential applications. An optional wire box
for the ProStar MPPT controller provides a wiring compartment with
knockouts for conduit and cable glands. It provides for a cleaner, safer
Features of the ProStar MPPT Controller:
- 12/24V Battery Auto Detect
- Advanced field adjustable load & lighting control built in
- Advanced battery programming including Lead Acid, Lithium Ion , and Nickel Iron batteries
- Continuous charging and no damage from oversizing PV array
- 4-stage charging: Bulk, Absorption, Float, Equalize
- Built-in self diagnostics for continuous monitoring of internal hardware issues or system problems
- Fanless design and vast operating temperature range make it suitable for extreme environments
- Very high weighted efficiency keeps power output high even at full power
- 190 days of internal data logging w/NEW graphical view on Meter versions
- Single RJ11 port that can be used for the Meter or for Data mode
- Electronic Protections: Automatic recovery without fuses; Solar Input: overload, short-circuit, high voltage, reverse polarity, high temperature, nighttime reverse current; Load Output: overload, short-circuit, high temperature, reverse polarity; Battery: reverse polarity (no battery removal)
- Certifications: CE; RoHS; UL1741/CSA.107.1; IEC 62109; FCC Part-15 class B
compliant. Mfr in certified ISO 9001 facility
- 5 Year Warranty
And check out these great benefits too:
You can apply more input on the controller than it is rated for.
Output current will be limited to the max controller current rating.
This allows for optimum usage of controller capacity.
The advanced electronic design offers long life and reliability. The
3 independently controlled high frequency MPPT stages use Morningstar's
TrakStar algorithm, giving you an additional 15-30% more power out of
your array versus a PWM solar charge controller.
The connections have up to #2AWG power terminals which are extremely
robust terminal connections for a controller of this size. This is
helpful when the controller needs to be a long distance from the array.
It is highly recommended to add the optional RTS (Remote Temperature
Sensor) as the reading will come directly from the battery, for a more
effective charging and monitoring of the batteries.
