Abysmal quality control, high failure rate
We are a company dealing in Solar equipment for the past 8 years. We have worked with ZL-power on multiple occasions, but due to quality deficiencies of their products have stopped cooperating. Overall, we have witnessed a failure rate >20% across all products, which is totally inacceptable. They get an extra star for at least some basic effort to solve these problems, i.e. sending spareparts - sometimes for free, sometimes for payment) and with this support, we get most systems running at least for a couple of years. so they are not an outright scam - they just work at the lowest level of quality control and are simply not reliable. not recommended for cooperation.
