Review on ⚡️ OutBack Power FM60-150VDC FLEXMax 60 Charge Controller - Advanced Solar Charging Solution by Adam Cooper

Last week I took the FM60 to Haiti (20th parallel). It was very hot and muggy. Connected to 8 x 190 watts 26v nom. Solar panels (4 connected in series, multiply by 2). The FM60 was very easy to set up and started charging right away. We used a 24 V battery (8 x 6 V, approx. 5 kWh). We needed more batteries as they charged very quickly. We also use a 3.5kW 24V inverter from batteries. We've outfitted it with heavy weights like a 3/4hp booster pump, a Grundfos downhole pump, a big miter saw and a big radiator. The FM60 never missed a beat. On the status screen you can see that the PV voltage is around 115 VDC and the FM60 is constantly monitoring the input power and maximizing the output power for the batteries. this. Input voltage x current = output voltage x current. Thus, almost all of the photovoltaic power is available for batteries (that's the beauty of MPPT). The maximum battery charging power was about 0.5 kW or about 20 amps (but I expect up to 60 amps with this configuration and heavy loads). I also saw the device charging very early in the morning and late at night, even though the current in the batteries was only a few amps due to the low light. Came up on the way but we were able to fix it quickly with needle nose pliers. Also, the fan is a bit noisy when it turns on from time to time. But of course it only worked during the day and the place was very quiet. In larger configurations, up to 30% increase easily saves additional MPPT costs with more power or fewer panels.
