Testing at the point where wires go into the SmartSolar input terminals with a Sun MPPT tester shows the optimal power point to be at 330 - 350W mid-day sun. But SmartSolar is locked at voltage and current suboptimal to this and only producing around 150 - 200W (max). Believe there is some configuration problem. Any thoughts on how to diagnose and fix. (Unfortunately another brand MPPT has locked correctly, which is why we suspect SmartSolar is not configured right in some way.)
Post the panel specs, the voltage & current the panel tester displays, and the pv voltage & current, and the battery voltage & current for the mppt.
Have you actually watched the 100/20 track? You can do this by setting up Victron Connect Trends on PV Volts and Amps, and max resolution (~per sec).
It will only track when it's trying to maximize power, and then only every 10 minutes. So if you're making load changes, etc, you'll need to wait up to 10 min for a reaction.
There's no configuration involved with the tracker itself.
Using BT and phone, we have watched the watts, voltage, and amps MPPT is putting out. It is a fraction of the available watts using the solar panel tester. We will read your response carefully and follow accordingly and check including giving minimum 10 min of time to see if there is a change. But wattage output is continuous and as said it is a fraction of what it should be. Thanks for suggestion!
