8KW 10KW Split Solar Storage Inverter
Instructions OSP series is a new type of solar energy storage inverter control inverter integrating solar energy storage & utility charging and energy storage, AC sine wave output. It adopts DSP control and features high response speed, reliability, and industrial standard through an advanced control algorithm.
Features
• Supports lead acid battery and li-ion battery connections.
• With a dual activation function when the li-ion battery is dormant; either mains or photovoltaic power supply access can trigger the activation of the li-ion battery.
• Supports single-phase parallel and parallel three-phase pure sine wave output.
• Stand-alone or parallel systems support 200, 208, 220, 230 and 240Vac voltage levels
• Supports two solar inputs and simultaneous tracking of two solar maximum power charging/carrying capacity functions.
• Dual MPPT with 99.9% efficiency and maximum 22A current in a single circuit, perfectly adapted to high power modules.
• 4 charging modes are available: solar only, mains priority, solar priority, and mixed mains and PV charging.
• Time-slot charging and discharging setting function is available in both off-grid and hybrid grid-connected modes. • Stand-alone energy saving mode function to reduce no-load energy losses.
• With two output modes of utility bypass and inverter output, with uninterrupted power supply function.
• LCD large screen dynamic flow diagram design, easy to understand the system data and operation status.
• 360° protection with complete short circuit protection, over current protection, over under voltage protection, overload protection, etc.
• Support CAN, USB, and RS485 communication.
• With N grounding option.
System connection diagram
The diagram below shows the system application scenario of this product. A complete system consists of the following components:
1. PV modules: converts light energy into DC energy, which can be used to charge the battery via an inverter or directly inverted into AC power to supply the load.
2. Utility grid or generator: connected to the AC input, it can supply the load and charge the battery at the same time. The system can also operate generally without the mains or generator when the battery and the PV module power the load.
3. Battery: The role of the battery is to ensure the regular power supply of the system load when the solar energy is insufficient and there is no mains power.
4. Home load: Various household and office loads can be connected, including refrigerators, lamps, televisions, fans, air conditioners, and other AC loads.
5. Inverter: The energy conversion device of the whole system. The actual application scenario determines the specific system wiring method.
2 Precautions for connecting the parallel connection cable
1. PV Wiring: When connected in parallel, different machines need to be connected to different PV arrays or PV sources. You cannot connect the same PV to different machines. The machine's PV1 and PV2 must not be be connected to the same PV source.
2. Battery Wiring: For single-phase or three-phase parallel connections, all inverse control units must be connected to the same battery, BAT+ to BAT+ and BAT- to BAT-. And make sure that the connections are correct and that the wires are of the same length and diameter before powering on the machine. Avoid wiring errors causing parallel system outputs improper operation.
3. AC OUT Wiring: a. Single-phase parallel lines When connecting single-phase parallel machines, all inverse control units must be connected L to L, N to N wire and PE to PE. And make sure that the connections are correct and that the wires are of the same length and diameter before powering on the machine. Avoid wiring errors causing parallel system outputs improper operation.
Wiring reference 2.4.3 Diagram. b. Three-phase parallel lines When connecting three-phase parallel machines, all inverse control units must be connected N to N wire and PE to PE. The L-wires of all machines in the same phase need to be connected together, but the Lwires of the AC outputs of different phases cannot be connected together. Other considerations as for parallel single-phase connection. Wiring reference 2.4.4 Diagram.
4. AC IN Wiring: a. Single-phase parallel lines When connecting single-phase parallel machines, all inverse control units must be connected L to L, N to N wire and PE to PE. And make sure that the connections are correct and that the wires are of the same length and diameter before powering on the machine. Avoid wiring errors causing parallel system outputs improper operation. At the same time, there must not be more than one different AC source input, avoiding damage to the inverter or external electrical equipment. Consistency and uniqueness of the AC source input is required. Wiring reference 2.4.3 Diagram. b. Three-phase parallel lines When connecting three-phase parallel machines, all inverse control units must be connected N to N wire and PE to PE. The L-wires of all machines in the same phase need to be connected together, but the Lwires of the AC inputs of different phases cannot be connected together. Other considerations as for parallel single-phase connection. Wiring reference 2.4.4 Diagram.
5. Parallel Communication Cable Wiring: Our parallel communication cable is a standard DB15 computer cable with shielding. When using singlephase or three-phase machines in parallel, each machine must be connected one out and one in. This means that the male connector (out) of the machine is connected to the female connector (in) of the machine to be connected. Does not allow local male connectors to connect to local female connectors. At the same time make sure that the parallel communication cable is tightened through the DB15 terminal screw, which avoids disconnection or poor contact of the parallel communication cable leading to system output not working properly or damaged.
