1. Introduction 1. Introduction 1.2 Packaging 1.1 Product Description The Solis RHI-HV 5G series is designed for residential hybrid systems, which can work with high voltage lithium ion batteries to maximize self-consumption rate. This product can operate in both ON-Grid and OFF-Grid modes. The Solis RHI-HV series hybrid inverters contain 3 different models which are grid support transformerless utility interactive inverters: RHI-1P5K-HVES-5G, RHI-1P7.
2. Safety & Warning 2. Safety & Warning 2.1 Safety The following types of safety instructions and general information appear in this document as described below: WARNING: DANGER: “Danger” indicates a hazardous situation which if not avoided, will result in death or serious injury. Electrical installations must be done in accordance with the local and national electrical safety standards.
2. Safety & Warning 3. Overview 3.1 Screen Solis RHI-HV series adopts a 7 inch color screen. It displays the status, operating information, and settings of the inverter. WARNING: Operations below must be accomplished by licensed technician or Solis authorized person. 3.2 Keypad There are four keys in the front panel of the inverter (from left to right): ESC, UP, DOWN and ENTER keys. The keypad is used for: WARNING: AC-BACKUP of RHI-HV series is forbidden to connect to the grid.
4. Installation 4. Installation 4.1 Select a Location for the Inverter To select a location for the inverter, the following criteria should be considered: WARNING: Risk of fire Despite careful construction, electrical devices can cause fires. Do not install the inverter in areas containing highly flammable materials or gases. Do not install the inverter in potentially explosive atmospheres. Install on a wall or strong structure capable of bearing the weight of the machine (30kg).
4. Installation 4. Installation 4.2 Mounting the Inverter 2.Lift up the inverter (be careful to avoid body strain) and align the back bracket on the inverter with the convex section of the mounting bracket. Hang the inverter on the mounting bracket and ensure the inverter is secure (see Figure 4.5) Dimensions of mounting bracket: Figure 4.3 Inverter wall mounting Once a suitable location has been found according to 4.1 using figures 4.3 and 4.4 mount the wall bracket to the wall.
4. Installation 4. Installation 4.3 PV Terminals Please ensure the following before connecting the inverter: NOTE: The installation shall meet the National Electrical Code, ANSI/NFPA 70 and Canadian Electrical Code wiring methods. Ensure the voltage of the PV string will not exceed the max DC input voltage (500Vdc). Violating this condition will void the warranty. Ensure the polarity of the PV terminals are correct. Ensure the DC-switch, battery, AC-BACKUP, and AC-Grid are all in their off-states.
4. Installation 4. Installation 2. Lead the AC cable through the cable gland and the housing. Over-Current Protection Device (OCPD) for the AC side 3. Remove a length of 40mm of the cable jacket and strip the wire insulation to a length of 18 – 19mm. To protect the inverter's AC connection line, we recommend installing a device for protection against over-current and leakage, with the following characteristics noted in Table 4.2: 4. Each of the terminals are labeled.
4. Installation 4. Installation Note: The battery fuses in the wiring box are replaceable. The replacement must be done by Solis authorized technicians only. Fuse specification: 600V, 30A. Note: Before connecting the battery, please carefully read the user manual of the battery and perform the installation exactly as the battery manufacturer requests. Cable connection steps: 1. Use slot type screwdriver to press the block on the top. 2. Insert the exposed copper part of the cable into the terminal. 4.6.
