Frequently Asked Questions

5kW Off grid Solar Inverter

What does parallel working mean for a solar inverter?

Parallel working refers to the ability of a solar inverter to work in conjunction with multiple units in parallel. This feature allows for increased power output and system scalability. By adding more inverters in parallel, homeowners can expand their solar system's capacity without compromising efficiency or performance. Parallel working also enhances system reliability, as the load is distributed among multiple inverters, reducing the impact of a single point of failure.

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 parallel communication function of the HSI5500?

This function allows multiple HSI5500 inverters to communicate with each other when they are operated in parallel. This is crucial for ensuring coordinated operation and efficiency in larger installations​

Does the HSI5500 off grid solar inverter have a current sharing detection feature?

Yes, in parallel operation, the HSI5500 includes a current sharing detection function. This ensures that the load is evenly distributed among all parallel-connected inverters, enhancing efficiency and reliability​

What is the dry contact function in the HSI5500 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 HSI5500 off grid solar inverter?

The HSI5500 off grid 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.
