EPEver Tracer4210AN vs. Victron SmartSolar 75/15 (x2).

Thought I'd share this. It's a cold front day with powerful down pours mixed with powerful sun and cloud reflections.

"Battery Power/Panel Volts" = EPEver.
MPPT2 / MPPT3 = Victron's.

Panels: Craigsolar 330W 41VoC. 1 panel per MPPT. All 3 mounted in one row side by side. In the order, EPEver, MPPT2, MPPT3.

The victrons produce, on average 30% more power than the EPEver. They also produce 10% more peak output.

The voltage plot shows why, possibly, the EPEver is lazy, slow and prefers to couple to the battery and PWM instead of track. The "blue gear" is gar more aggressive.

Caveat:
EPEver measures EPEver.
Victron Measures Victron.
There is no independent verification of the values done, not even correlation with battery power. So the EPever could be under-reporting and/or the vitrons over reporting. The "shape" and "trends" should still hold ground in the data though.
