   This MPPT controller uses both mechanical and electronic components for power control. I like how rugged the unit is with old school mechanical relays for connecting and disconnecting the solar inputs. It’s a bit noisy at the twilight hours between sunset and dusk with the mechanical relays toggling between closed and open. The unit also produces a small high pitch electrical hum that can be heard if you’re nearby the unit. I uploaded a video that has this electrical hum. It only makes noise during the period between sunset and twilight when the solar panels are barely producing power. The unit seems very rugged and I felt confident switching inputs with a transfer switch without worrying about power arching. If you connect a panel during midday with 500 watts of power I’ve seen some controllers arch at the switch. The unit handled near 600 watts of power from two large panels in series with a moderate amount of fan noise. The MPPT performance for tracking the voltage/power was consistent but not as fast as some controllers on cloudy days. The controller managed to stay near the peak power curve for the panels connected but seems less efficient in the conversion of power to the battery than some controllers. I connected the MPPT controller to a bank of large LFP batteries with 20KWh of storage and it had no issues with the controller. Solid build and design and it worked reliably so far.

   I got this to upgrade my existing system from 30 amp to 60 amp. It was a fairly simple upgrade. This comes with descent instructions and I had it up and running in only a few minutes. It is a lot bigger then my previous one so I had to make room for it. So far it is running great and the display provides me a lot more information than my other one. Overall, it is a nice controller and it works great.
