Off-grid inverters, also known as stand-alone inverters, are designed specifically for solar energy systems that are not connected to the grid. Solar power systems store DC power in batteries for use in off-grid inverters, or they can be converted to AC power by a separate source such as batteries.
(1) different sources of power supply, off-grid solar inverter charger power supply source is the solar energy through the solar panels converted to direct current for off-grid solar inverter charger power supply, ordinary inverter is directly using the battery current for the inverter power supply, and the use of the grid for battery charging.
(2) the use of different places, ordinary inverter suitable for the existence of the grid will be the battery as a backup energy, can charge the battery for the place to prevent the trouble when the power outage, the solar inverter charger connected to the solar panels, in the absence of the grid can be independent of the power production.
(3) Benefits are different, solar inverter charger autonomous generation of electricity for living can save energy expenses can also reduce carbon resource emissions, there are higher economic and environmental benefits. At the same time, the solar inverter charger will be used in the process of generating electricity is gradually counterparts, ordinary inverters will not produce additional economic.
(4) Composition is different, compared with the traditional inverter solar inverter composition to more charge controller and blocking diodes, charge controller to ensure that the charging is overcharged, blocking diodes to ensure that the current single-phase output.
(5) Scope of use, ordinary inverters can be used in a variety of scenes where batteries exist, solar inverter charger is bound to solar panels more limited.
(6) Efficiency is different, solar inverter charger than ordinary inverter has higher efficiency and low energy consumption, can most increase the benefit of solar power generation.
Most off-grid solar inverters include a charger, which is used to charge the batteries in winter with a backup generator. The charger generally has a limited amount of charging power, and better quality off-grid inverters generally have 50 to 100 amps.
(1) RV travel, solar RV travel has become the preferred choice for RV travel, RV travel most of the time can not have a suitable charging location, in order to meet the RV’s power needs, the solar inverter charger is better than the traditional inverter at this time.
(2) No electricity (lack of electricity) areas, in Africa and the Middle East or war-prone areas, the transmission of electricity can not be effectively guaranteed, the use of solar inverter charger for the installation of solar panels is more effective, the use of ordinary inverters can not guarantee the charging of the battery, the source of solar energy is also no cost to ensure that to meet the most basic power needs.
Ordinary inverters have a wider range of use than solar inverter charging, but for solar panel systems solar inverter charger has better results.
