SONAR Parallel Installation Guide PART1: Single Phase Parallel System Wiring Lux power inverter support "Parallel Connection", which means you can combine multiple inverters together to get bigger back-up power. As parallel model is different from standard one, please make it clear to the distributor if you want a parallel unit. This document is used to show how to set up a parallel system. Step1. Single unit installation Install each single phase inverter as user manual. Before installation, please make sure the distance between each inverter meet the requirements of user manual. Step2. Parallel system wiring If you paralleling the system as single phase system, the most important thing is to make sure the L & N lines of each unit (AC port And EPS port) are correctly connected, please check with multi-meter to make sure L cable of each units are connected. Do not connect one inverter's L cable to another inverter's N cable. Wiring the parallel system as below suggestions for safety and cost reasons.

TYPE selection as SA1. And the current and capacity depends on the AC OUTPUT loads. !!Be sure the SA2 is only used when all inverters is power-off. Step3. Set up the parallel CAN communication balance resistance. Connect parallel communication cable. The port4 are used for parallel connection. Switch are used for the parallel communication balance resistance. If there are more than two inverters parallel in your system, only two of longest distance of need to be dialed toward "on "position: , and others keep off: 12PCS For other ports' definition, please refer to user manual. Please double check if the wirings are correct. The parallel port are pin-to-pin with each other for PIN1~PIN8, and you can buy this easily in any computer shop Step4. Set up the monitor system and do settings Power on the inverter and connect Wi-Fi to dongle to internet. For parallel system battery connection, we support 2 ways to connect, you can either connect all inverters to one battery bank or connect each inverter to separate battery group. Or it is connected as each inverter conncet to separate battery. If you connect one battery bank shared by multiple inverters as the diagram above, please enable "Battery shared". Step5. Running the system Check all connection and make sure is correct. Power on all Units and Check the all AC output is OK Turn on all breakers PART2: Three Phase System Wiring Step1. Install each single inverter as user manual Lux power inverter support three phase system, which means 3 pcs or more inverters can be used to compose a three phase system. Please note that this model is different from the standard one, please make it clear to distributor to get parallel unit. This document is used to show you how to set up a three phase system. Step2. Parallel connection Wiring the parallel system as below suggestions for safety and cost reasons. When paralleling the system as three phase system, make sure there is at least one inverter in each phase. DO NOT connect AC Output terminals all together when used in 3 phase system, otherwise you will short the grid/utility.
