Solar inverters can be divided into three categories: off-grid type, grid-connected type and hybrid type. The differences are as follows:

Item Off-grid inverter Grid inverter Hybrid inverter

Features System power is average and cost is low The system has high power and low cost, reducing grid expenses. The power of the system is high and the cost is high
Technology transistor IGBT power module or transistor MPPT or PWM technology
System Components Photovoltaic modules, inverters, controllers, batteries, combiner boxes Photovoltaic modules, inverters, controllers, smart meters, AC switches Photovoltaic modules, inverter and controller integrated, smart meter, AC switch, battery
Application Remote areas without power network coverage such as deserts, plateaus, and deep forests Where the city grid is strong enough, but power is insufficient The city power grid is always shut down and the power is not strong enough.

Photovoltaic inverter (PV inverter or solar inverter) can convert the variable DC voltage generated by photovoltaic (PV) solar panels into an inverter with mains frequency alternating current (AC), which can be fed back to the commercial power transmission system or supplied to the power grid. The power grid of the network is used. The photovoltaic inverter is one of the important balance of systems (BOS) in the photovoltaic array system and can be used with general AC power supply equipment. Solar inverters have special features that work with photovoltaic arrays, such as maximum power point tracking and islanding effect protection.

Photovoltaic solar inverters are divided into three categories according to their uses: grid-connected inverters, off-grid inverters, and microgrid energy storage inverters. Grid-connected inverters can be divided into micro-inverters and group inverters according to their power and uses. There are four categories: string inverter, centralized inverter, and distributed inverter. Centralized inverter systems have large total power and are mainly used in large-scale projects such as ground photovoltaic power stations with good lighting conditions; distributed inverters can be divided into string inverters and micro-inverters, which are usually used in small and medium-sized Industrial, commercial and household photovoltaic power generation systems, of which string type is the main type of distributed inverter product. Distributed inverters have the characteristics of both centralized and string types, and have been used to a certain extent in projects such as Mountain Leader. The micro-inverter tracks the maximum power peak of each photovoltaic module individually, and then integrates it into the AC grid after inversion. The single capacity of the micro-inverter is generally less than 1kW.

The market for inverters/converters in 2014 is as follows:

type power efficiency market share annotation
Module inverter Power range for vehicles 96.8% - -
String/cascade inverter 0.5kW to 5kW, up to 100 kWp, for private residences 98% 50% €0.15 per WP, easy to replace
Centralized/central inverter Above 100 kWp, 60kW to 1MW, used in large solar power plants 98.5% 48% €0.10 per WP, highly reliable, sold with service contract
Multi-string inverter 3kW to 30kW for medium-sized rooftop or ground systems 98% - -
Microinverter Photovoltaic module power range 90%–95% 1.5% €0.40 per WP, but easily replaceable
DC-DC converterPower optimizer Photovoltaic module power range 98.8% Not suitable Each WP is €0.40, but there is the problem of easy replacement and inverters are still needed. In 2013, about 0.75GWP was installed.

Inverters can be divided into different types according to different use occasions and requirements, such as power inverters, UPS inverters, photovoltaic solar inverters, etc. A solar inverter effectively converts the DC power generated by solar panels into AC power that can be used for home or commercial purposes. Here are some of the main advantages of solar inverters:

1.
