Page 22: Hard-Wire Installation 1
DC Input Voltage Model Minimum Maximum 4-2. Hard-wire Installation: 4-2-1 SD series provides the flexibility of hard-wire connection, and this function will make external control panel wiring easier. Step 1. > Remove the four screws of AC wiring compartment and pull it out with care. - Page 23 100VAC~120VAC / 200VAC~240VAC System NOTE: The only difference between 110V and 220V is within the AC Input breaker L or N and thus will not affect the wiring configuration. 4-2-2 Connect AC output and AC input wiring to the SD series terminals. Please take the following information as your reference.
- Page 24 the “N” terminal of the AC input source. If the AC input source is the power supplied from the utility, the “N” terminal would be a Neutral in the true sense. It will normally be bonded to the earth ground and will read almost 0 V with respect to the earth ground.

Parallel Unit 1 Unit 2 Unit 3 Parallel Jump OFF* * If you parallel N units, the first (unit 1) and the last unit (unit N) must set parallel jumper in ON position. NOTE: SD series can be used for N+1 (N≦14) redundancy and the ability of enlarge the capacity (Users can install maximum 15 units of inverters together in parallel in order to provide the power expansion). - Page 27 Not prefer to use different battery-bank attery- attery- configuration because batteries voltage is bank 1 bank 2 difficult to control.

5-2-3 Remove Parallel Connection 1. If “A” and “B” was used in parallel, we only need to operate one of them. 2. In the parallel mode, the first SD turned on will be the master. 3 . If we just want to use only one of SDs, we can just remove RJ45 cable, but make sure the operation is performed in shut-down mode. -
