from this post about fake Chinese MPPT:
![yrbpwkavhtvd](https://boondockplan.files.wordpress.com/2018/09/yrbpwkavhtvd.jpg)Here's [a pic of] one of the fake units. These are typically about $45.00 or so. Anything less guaranteed fake. The real ones online pricing start about $120.00 for the basic imported models.
Note: that really is a fake MPPT (PWM or shunt labeled as MPPT). That’s not the problem. As is too often the case, we have a knowledgeable person overstating a case. This does not help the original poster or onlookers.
Anything less guaranteed fake.
No. There are at least two counterexamples.:
early versions of the CPY-2410 were about $25 and were doing actual MPPT. Later versions are dumbed down to do only DC-DC conversion.
The MPT-7x10A boosting type is indeed an MPPT controller which runs $35-$45.
The real ones online pricing start about $120.00 for the basic imported models.
Again, two counterexamples come directly to mind:
Ecoworthy pricing starts around $80.
Both of these start around $80 including shipping.
moral of the story
Experts with an audience of solar-newbie onlookers really should stick to the facts. Well-supported arguments/answers/explanations are compelling on their own and do not require the decoration of hyperbole.
