10 kW 48 V Split-Phase Solar Inverter
10 kW 48 V Solar Inverter Split-Phase – The SPH U series is a new type of solar storage inverter that integrates PV storage, mains charging, energy storage, and outputs sinusoidal AC. Equipped with DSP control and an advanced control algorithm, it has a high response speed and good reliability and is suitable for industrial scenarios.

10 kW 48 V Solar Inverter Features
- Supports the connection of various types of energy storage batteries, such as lead-acid batteries and lithium-ion batteries
- Has the dual activation function during lithium-ion battery sleep; that is, access tomains/PVpower can activate the lithium-ion battery
- Supports split-phase/single-phase pure sine wave output
- Support adjusting the voltage of each phase within the range of 100 VAC, 105 VAC, 110 VAC, 115 VAC, 120 120VAC,127VAC
- Support two-channel PV input and have the function of simultaneous two-channel Max. power point tracking (MPPT) for charging/carrying capacity
- Support two-channel MPPT, with an efficiency of up to 99.9% and a maximum single-channel current of 22 A, perfectly fitting high-power modules
- Provide four charge modes: only PV, mains first, PV first, and mains + PV
- Have the timed charge and discharge function; that is, users can set the charge and discharge time according to the time-of-use price to save electricity costs
- Have the energy-saving mode, reducing no-load energy losses
- Provide two output modes: mains bypass output and inverter output, achieving uninterrupted power supply
- Support LCD display of dynamic flowchart, updating system data, and operating status at any time
- Provide 360° protection, including short-circuit protection, overcurrent protection, overvoltage and undervoltage protection, and overload protection
- Support CAN, USB, and RS485 communication
System connection diagram
The following figure shows the system application scenario of the product. A complete system consists of the following parts:
- PV module: It converts solar energy into DC to charge batteries or into AC to supply power to loads.
- Mains or generator: Connected to the AC input, it can charge batteries while supplying power to loads. When the battery and PV module supply power to the load, the system can generally operate without a mains or generator.
- Battery: The function of a battery is to ensure normal power supply for the system load when there is insufficient PV power and no mains.
- Household load: It can connect various household and office loads, including refrigerators, lighting fixtures, TVs, fans, air conditioners, and other AC loads.
- Inverter: It is the energy conversion device of the entire system
