Frequently Asked Questions

10kW Split Phase Inverter

What are the pros and cons of low-voltage batteries?

Pros of low-voltage batteries include lower cost, easy maintenance, and better compatibility. They are more affordable, require less effort to maintain, and work well with various systems.

However, there is a drawback. When the accumulative current in the system becomes too large, it can potentially lead to safety and efficiency issues.

But for residential storage systems below 20kWh, low-voltage batteries are a more balanced and economical choice.

What is the dry contact function in the off grid solar inverter?

The dry contact function allows the inverter to control a diesel generator's switch for charging the battery. It automatically activates the generator when the battery voltage is low, ensuring continuous power supply

What are the different charging modes available in the inverter?

The SPI-10K-U split phase solar inverter offers versatile charging modes to accommodate various energy needs and scenarios. These modes include:

  1. Solar Power Mode: In this mode, the inverter primarily uses solar energy to charge the battery. It's an eco-friendly option that maximizes the use of renewable energy. Ideal for sunny days when there's ample solar power available.

  2. Mains Power Priority: This mode gives preference to mains (grid) power for charging the battery. It’s useful when solar energy is insufficient, like during cloudy days or at night. The inverter will automatically switch to solar charging when mains power is not available or is more expensive.

  3. Solar Power Priority: Opposite to the mains priority, this mode prioritizes solar power for charging. The inverter will switch to mains power only when the solar energy is not adequate to meet the load demand. It's perfect for locations with high solar energy availability and for reducing reliance on the grid.

  4. Mixed Charging (Solar and Mains Power): This mode combines both solar and mains power for charging. It intelligently balances the use of solar and grid power, ensuring efficient energy usage and constant power supply. Ideal for maintaining a continuous power supply in varying environmental conditions.

  5. Generator Charging: If connected to a diesel generator, the inverter can also use it for charging, especially useful in areas with limited grid access or during prolonged power outages.

What are the AC output modes available in the split phase solar inverter?

The inverter offers several AC output modes, including Utility Priority Output, Solar and Utility Hybrid Output, Solar Priority Output, and Inverter Priority Output. These modes allow users to prioritize power sources based on availability and need​

Can the split phase solar inverter manage power usage based on electricity rates?

Yes, it features a time-slot charging and discharging function that lets users set different charging and discharging periods based on local electricity rates. This helps in using utility power and solar energy more efficiently and can lead to significant cost savings

What types of batteries can be connected to the split phase solar inverter?

The inverter supports both lead acid and lithium-ion battery connections, offering versatility in energy storage options.
