Note: Disconnect the system in the reverse order. Namely, disconnect the
system in the order of ④ PV array -- ③ battery -- ② load 2-- ① load 1.

Step 3：Grounding
MSC-N series are common-negative controllers; all the negative terminals can be
grounded simultaneously, or anyone is grounded. However, according to the
practical application, the negative terminals of the PV array, battery, and load can
also be ungrounded. Still, the grounding terminal on the shell must be grounded. It
effectively shields the electromagnetic interference from the outside and prevents
some electric shock to the human body.

you must connect the inverter directly to the battery, not to the load
