Commercial Inverters for Solar & Battery Systems

Commercial inverters are designed to handle the scale of power production and consumption required for large projects. The main role of the commercial inverter is to convert of Direct Current (DC) into Alternating Current (AC). If the system includes battery storage, an inverter can also help facilitate storing excess solar power in the batteries or charging them from the grid. Commercial properties often use three-phase power, commercial three-phase inverters are designed to sync with three-phase power, providing a more consistent flow of electricity.

The correct choice of inverter for a commercial solar and battery system will depend on a number of factors, including the size and configuration of the solar array, whether there is a battery storage system, the type of electrical system in the building, and local regulations and utility policies.

The commercial solar inverter is a device designed to convert the DC power generated by solar panels into AC power and combine it with an energy storage system for energy management and optimization.

In commercial and industrial environments, it can be used for power storage, load scheduling, peak and valley tariff arbitrage, improving grid stability, and as a backup power source.

Concepts and principles of commercial solar inverter

• The commercial solar inverter integrates the inverter of the photovoltaic power generation system and the charge/discharge control function of the energy storage system. When the solar energy is sufficient, it not only drives the loads, but also stores the excess power in the battery; When the solar energy is insufficient or the power grid is down, the stored power is released from the storage device for use by the customer.
• The commercial solar inverter is usually equipped with bi-directional conversion capability, i.e., it can convert AC power into DC power to be deposited into the battery in charging mode, and invert the DC power in the battery into AC power to meet the requirements of grid quality in discharging mode.

The role of commercial solar inverter

• Increase self-sufficiency and reduce dependence on the public grid.
• Smoothing the volatility of photovoltaic power generation and improving the stability of power supply.
• Utilizing the difference between peak and valley electricity prices to reduce the cost of electricity consumption for enterprises.
• Participate in demand response services to assist in the stable operation of the power grid.
• Provide emergency power protection in case of grid failure.

Prices of commercial solar inverter

Prices for commercial solar inverters vary by brand, model, power rating, feature configuration, technical complexity, and other factors, and usually have a wide price range. The following information may provide a general reference:

1. In September , Sungrow announced the price of commercial and industrial liquid-cooled energy storage system PowerStack 200CS series as 1.56 RMB/Wh in its new product launch event, and the larger the purchase volume, the more the unit price discount.

The company is the world’s best how to size solar inverter supplier. We are your one-stop shop for all needs. Our staff are highly-specialized and will help you find the product you need.

The price here is calculated based on the comprehensive cost of the whole energy storage system, not just the inverter part. However, for understanding inverter prices, this data can help us understand the overall cost structure of high-end energy storage solutions currently on the market

2. Specifically, the price of a single inverter item is usually quoted on a cost per kilowatt (kW) or megawatt (MW) basis. For example, different commercial solar inverter suppliers may sell from a few thousand dollars to hundreds of thousands of RMB depending on the power of the device.

3. commercial solar inverter may include both grid-connected and off-grid models, as well as whether or not it has features such as battery management system (BMS) integration, intelligent scheduling, and grid support services, all of which will affect its final selling price.

Industry forecast for commercial solar inverter

The following are some of the key trends in the commercial solar inverter market in the coming years:

Installation requirements for commercial solar inverter

As the core equipment of the power station, the installation of commercial solar inverter is not done properly, which will directly affect the normal power generation, and even produce safety hazards. So, what are the places to pay attention to the installation of commercial solar inverter?

• Ensure that there is no strong electromagnetic interference from other electronic or electrical equipment at the installation location.
• During the operation of commercial solar inverter, the humidity of the chassis and heat sink will be relatively high, please do not install the commercial solar inverter in a position that is easy to touch.
• Commercial solar inverter should be installed in a well-ventilated environment to ensure good heat dissipation.
• It is recommended to choose a sheltered installation location or build an awning.
• The ambient temperature of the installation should be -30-60°C and the site should be clean.
• The installation location should be on a fixed and solid surface, such as a wall, metal bracket, etc. The inverter should be mounted on a reliable surface.
• The installation location should ensure that the inverter is reliably grounded, and that the grounding metal conductor material is the same as the inverter's reserved grounding metal material.

Installation considerations for commercial solar inverter

• Before commercial solar inverter installation you should first check that the inverter has not been damaged during transportation.
• Always cover the PV panels with impervious material or disconnect the DC side circuit breaker before making electrical connections. Exposed to sunlight, the PV array will generate dangerous voltages.
• All installation operations must be performed and only by specialized technicians.
• The cables used in a PV power system must be securely connected, well insulated, and of the proper gauge.
• All electrical installations must meet local and national electrical codes.
