CMTP02 — disassembling this solar charge controller — DIY Projects I want to share inside look of cheap Chinese solar charge controller CMTP02 (CMTP-02). I have a 30A (charging current) variant, but it has also 5A, 10A, 15A, 20A version . This is should be a PWM controller. Protect your valuable solar installation and maximise battery service life with our photovoltaic (PV) charge controller. This little black box does it all, efficiently and consistently. All three was the same (if I remember correctly) And finally- picture of manual.
The Genasun 5A MPPT solar charge controller adapts to changing light conditions 15 times every second. Current Limiting Current limiting is provided by the solar panel –it is not a commonly understood fact that the solar panel tends to be a constant current device. Genasun worked to eliminated RF emissions from our line of charge controllers. They endure years at sea, harsh Antarctic winters, freezing conditions in the upper atmosphere on solar powered airplanes, and in a few off-the-map locations.
Traditional controllers have components filled with liquid electrolytes that boil off over time, causing system failure. Mission-Critical ReliabilityGenasun controllers are deployed to the most remote locations on earth. Low Dropout Voltage (LDO) is the catch phrase for anything under approximately 2V. This could potentially be reduced to below 1V by making D3 a schottky rectifier. Someone who has used it with higher loads can comment- is it enough and how well it works.

Probably controlling? I didn’t look up their datasheets. The controller will automatically test to see when the short is removed.
