PV output (watts not volts) falls as inverter load increases. How can this be corrected?

While bulk charging batteries alone, PV output stays at about 1400 watts. When a 700 watt load is turned on on the multiplus, PV output mysteriously falls to about 900 watts.This occurs while still in bulk charging mode. One of my mppt's is throttled down to very low output even though it's in constant sun.


I'm running 3 Smart Solar MPPTs,BMV-712, a CCGX (DVCC on, SVS, STS, SCS on, Max charge off) and a Mulitplus compact connected via an MK3.


Any suggestions to fix this and keep the 1400 watt output from being throttled down?

The problem has been corrected. It required firmware updates on all components.
