(3)PV Cross-Source Error: The SolarFlow 800 features two independent PV ports, each corresponding to an
independent MPPT. The connection method shown in the diagram artificially parallels two originally independent PV
ports. This wiring method leads to a PV cross-source issue, causing uneven power distribution between the two PV
ports and potentially damaging the product.
7.3.4 Connect to the Grid
(1) Select the appropriate Circuit
When connecting the SolarFlow 800 to a home or business branch circuit, it's important to choose the right
configuration to ensure safe and efficient operation.
Configuration A
Branch Breaker
Neutral
Ground
This configuration is unsuitable for SolarFlow 800 as it includes multiple loads, such as receptacles, lights, and high-
power appliances (e.g., dishwashers, laundry machines). These unpredictable and high-current loads increase the risk
of exceeding branch circuit limits during solar production.
Branch Breaker
Neutral
Ground
This setup is ideal for connecting the SolarFlow 800 as it contains only receptacles. Each receptacle can be individually
protected using the methods outlined. If there are unused slots in your distribution panel, an electrician can implement
this configuration at a relatively low cost.
(2) Plug to the Socket
Using the provided AC power cord, first connect the cable to the SolarFlow 800, then plug it into a household power
outlet on the appropriate circuit.
