According to android app, MPPT 150/70 power from panels is affected by load on battery in same system. When load, MPPT power drops accordingly. Is that a feature in monitoring or does the battery load actually affect negatively to solar power gain? Load is made by Multiplus II and measuring device is BMV-712 which is connected to MPPT by VE.Smart.
Need more details about your PV array. So, tell us ... How many volts, amps and watts is the PV Array producing when the load is off vs when the load turns on? The BMV-712 is measuring the volts and amps, in / out of the battery bank. The amps charging the battery bank will decrease when the load is on.
Here is an example. Down spike is fridge.
That could be it, didn't know such feature exists. And curve history gets smoothed out so maybe that's why it's not seen in longer history.
You’re probably close at your controller’s maximum output current. What’s happening is, depending on the voltage of the battery, power output changes, since P=V*I, while MPPT output current stays steady. That’s normal.
