Review on Mars Rock Inverter 20 50VDC 90 140VAC by Seth Torres
QC is really bad. - Solar and wind energy
The quality control on these machines is a disgrace. I have bought 3 pieces in the last few months. The first had no manual or power cord. The second was a fire hazard: there was no plastic backing on the B+ and B- terminals INSIDE the unit. This would short out my panels if I didn't notice. The third block had a broken QC seal as well as 1 broken and 1 missing screw. Blocks work but only expect 70% efficiency.
Pros
- Ideal electrical protection. Aluminum alloy body, anti-rust, heat-resistant and cold-resistant, as well as anti-corrosion.
Cons
- I don't have much aversion to it, everything is fine
