Solar Inverter with Split Phase

Solar Inverter with Split Phase is a photovoltaic device designed for specific grid standards (e.g., 120V/240V split-phase systems in North America), and its core advantages are to adapt to the split-phase power supply topology, balance load distribution, and improve system compatibility, which plays a key role in domestic and small business scenarios. The following is an explanation of the core advantages and practical effects:
First, the core advantages and the corresponding practical role
1. Adapt to the standard of split-phase power grid and directly connect to the local power supply system
Advantages: Support 120V/240V dual voltage output, in line with the civil power grid specifications in North America, South America and other regions (in the split-phase power supply system, the live wire is divided into two 120V phases, the phase difference is 180°, and the line voltage is 240V).
Function: No additional transformer or voltage converter is required, and can be directly connected to the local grid or off-grid system, avoiding power loss due to voltage mismatch (traditional single-phase converters require additional conversion, reducing efficiency by 2%-5%). For example, a 120V load (e.g., lamps, small appliances) in a home can use one of the phases directly, while a 240V load (e.g., air conditioner, electric water heater) uses a two-phase line voltage to simplify system wiring.
2. Balance the single-phase load to avoid circuit overload
Advantages: Split-phase design dynamically balances the two-phase current by distributing loads of different power to two 120V phases.
Function: Solve the problem of "high-power equipment concentrated in one phase leading to overload tripping" in single-phase converter. For example, if a 120V refrigerator (1.5kW) and a 240V oven (3kW) are used in a home at the same time, a split-phase inverter will assign the refrigerator to phase A, and the two-phase current of the oven will be borne by phase A and phase B, respectively, to avoid excessive phase A currents (traditional single-phase converters can cause phase A currents to exceed the circuit breaker threshold).
3. Improve system compatibility and support mixed load types
Advantages: Compatible with both 120V low-voltage equipment and 240V high-voltage equipment, there is no need to configure the inverter separately according to the load voltage level.
Function: Reduce the complexity of system design, especially suitable for scenarios with various load types. For example, in a small farm, a 120V irrigation controller, a 240V water pump and a 380V compressor (converted by a split-phase transformer) can share a single split-phase inverter, reducing equipment procurement costs (saving more than 30% of the initial investment compared to configuring multiple inverters).
4. Optimize energy distribution and improve photovoltaic utilization
Advantages: Combined with the energy storage function of the hybrid inverter (such as the integrated split-phase inverter of photovoltaic and storage), the proportion of photovoltaic power supply of the two phases can be dynamically adjusted.
Function: When the light is unstable, the photovoltaic power is preferentially distributed to the phase with high power demand, and the remaining power is stored in the battery. For example, if the air conditioner in phase B consumes a lot of electricity during the day, the inverter can allocate 70% of the PV power to phase B and 30% to phase A to avoid wasting excess electricity. At night, the battery supplies a balanced power supply to the two phases, reducing the dependence on the grid
