I currently have 2 EG4 6000XP inverters, connected to 3 LL4 batteries and the 12 485w panels. The panels are arranged in 3 arrays of 4 panels each. 1 inverter has a single array attached and the other 2. I've done this in order to study the effect of any differential shading and direction. The inverters are in parallel mode with shared battery. The batteries connect to buss bars with #6 cables about 6 ft long. Inverters to the buss bar with shorter lengths of #4. The AC output of each inv feed into a combiner panel and from there to a load panel at the house, #4 through a breaker. 240V grid power comes in to the equipment room from the houses main panel to a smaller load box where it is shared with the two inverters through 30A breakers. The loads, which have been removed from the house's grid system, at this time are a mini split, a 15A cct for kitchen outlets, and a 15A circuit for a home entertainment system.
My question:
In the attached screen shot from solar assistant, even though the system batteries are at 100%, there are occasional drops in system voltage on the order of seconds, or parts of seconds, that trigger the inverters to connect grid for that short period. Occasionally this has triggered a restart of my TV, even though it is connected through its own UPS. None of this is reflected on the EG4 monitor system as it lack the granularity. Can you help me to understand this and whether or not I should seek some solution,
