Page 31: Appendix Ii: Parallel Function
Appendix II: Parallel function 1. Introduction This inverter can be used in parallel with two dif f erent operation modes. 1. Parallel operation in single phase with up to 6 units. The supported maximum output power is 14.4KW/18KVA. 2. Maximum six units work together to support three-phase equipment. Four units support one phase maximum. - Page 32 Step 4: Simply slide in the parallel board and fix it to the inverter with 2 screws tightly. Now the inverter is in parallel operation. 4. Mounting the Unit When installing multiple units, please follow the illustration below. NOTE: For proper air circulation to dissipate heat, allow a clearance of appr ox. 20 cm to the side and approx. 50 cm above and below the unit.
- Page 33 Regarding AC input and output, please also follow the same principle. CAUTION!! Please install the breaker at the battery and AC input side. This will ensure the inverter can be securely disconnected during maintenance and fully protected from over current of battery or AC input. The recommended mounted location of the breakers is shown in the parallel diagrams in section 5-1 and 5-2.

- Page 43 NOTE: Master and slave units are randomly def ined. Step 4: Switch on all AC breakers of Line wires in AC input. It’s better to connect all of the inverters to the utility at the same time. If not, it will display fault 82 in the following inverters. However, these inverters will automatically restart.
- Page 44 Note 1: To avoid overload occurring, before turning on breakers at load side, it’s better to have the whole system in operation first. Note 2: There is some transfer time for this operation. Power interruption may happen to critical devices, which cannot tolerate transfer time.
- Page 45 and output cables are in the same length and in the same material type. If the problem remains, please contact your installer. Switch off the inverter and check LCD setting #28. For parallel system in single phase, make sure no 3P1, 3P2 or 3P3 is set AC output mode on #28.
