3. Installation 2. Safety & Warning 3.1 Select a Location for the Inverter To select a location for the inverter, the following criteria should be considered: WARNING: Exposure to direct sunlight may cause the output power to decrease. It must install Solis requires using two magneto-thermic automatic switchs with an RCD the inverter indoors and avoid direct sunlight and rain.
3. Installation 3. Installation 3.2 Mounting the Inverter 3.3 Preparation Before connecting all wiring, please take off the bottom cover by removing the screws as shown below. WARNING: The inverter must be mounted vertically. Select the mounting height of the inverter and mark the mounting holes. It’s recommended to install the inverter tighten by using two M5 screws.
3. Installation 3. Installation 3.4 PV Input Terminal Assembly 3.5 Assembling the AC Connector Please ensure the following before connecting the inverter: To protected from over current of AC input, Solis recommends installing a separate AC breaker between the inverter and the AC input power source. Make sure the voltage of the PV string will not exceed the max DC input voltage This AC breaker should be at least 32A.
3. Installation 3. Installation 3.6 Grounding 5. The dry contact is used for an onsite generator. To effectively protect the inverter, a grounding methods must be performed. Connect the external grounding terminal. Description Signal Name To connect the grounding terminal on the heat sink, please follow the steps below: RELAY1_NC 1.
3. Installation 3. Installation 3.7 Battery Terminal Components 3.7.3 Battery Connection 3.7.1 Lead-acid Battery To avoid DC Arcs, Solis recommends installing a DC switch between the battery(s) and inverter. If you choose a lead-acid battery, the allowed battery types are AGW-type, Ensure the cables within the suitable specifications as shown in the table below.
3. Installation 3. Installation 3.8 Battery Communication 3.9 External Communication The EO Series inverter uses RS485 cable to communicate with port to RS-485 is one standard communication interface which can transmit the real data from BMS/NTC communicate with the BMS of Lithium and NTC of Lead-acid battery. inverter to PC or other monitoring equipments.
3. Installation 3. Installation 3.10 Parallel Connection 3.11 External Communcation Stick Connection Inverter provides a Monitoring port which can collect data from inverter and transmit it to The "-P" type in the EO series inverter has the parallel capability and can be operated monitoring-website via an external monitoring data collector.
4. Commissioning 5. Operation 4.1 Preparation of Commissioning 5.1 Startup guide Ensure all the devices are accessible for operation, maintenance and service. Please follow the steps to complete the initial setup process. Check and confirm that the inverter is firmly installed. Steps: Ensure space for ventilation is sufficient for one inverter or multiple inverters.
