Does an off-grid inverter have to be equipped with a battery? The answer is not necessarily. Lolsolar off-grid inverter, in addition to the basic functions of conventional off-grid inverters, users can also choose a battery-free operating mode. Let’s take a look at how an off-grid inverter works without a battery.
In some places where electricity prices are relatively high and power outages are frequent, installing photovoltaic systems is a good choice. However, the grid-connected system cannot generate electricity during a power outage, which wastes part of the energy, and the equipment cannot work, affecting the continuity of work. If a photovoltaic off-grid system is installed, photovoltaics can continue to generate electricity during a power outage without affecting the continuous operation of the equipment, and the overall benefits are better. However, conventional off-grid systems require a large number of batteries. These energy storage batteries are expensive and have short lifespan, which increases the initial investment cost of the system. Therefore, the application of photovoltaic off-grid systems is also limited. The inverter output power is 5kW. In addition to the basic functions of conventional off-grid inverters, photovoltaic priority working mode, mains complementary working mode, and battery working mode, a battery-free working mode is also added. Battery-less mode means that when the system has no battery or the system has a battery but the battery is dormant for some reason, the inverter can still ensure normal operation when there is sufficient photovoltaic power.
- When the system has photovoltaic and commercial power, the 5kw can be similar to a grid-connected inverter and can be connected to the grid for spontaneous use. When the photovoltaic power is less than the load power, all the photovoltaic energy is supplied to the load, and the insufficient part is supplemented by the mains power, and the photovoltaic and mains power jointly carry the load. When the photovoltaic power is greater than the load power, the photovoltaic energy is provided to the load first, and the excess energy can be used to charge the battery. If there is no battery, the inverter will adjust the power generated by the photovoltaic based on the current load to ensure that the inverter does not send power to the grid.
- When the system has photovoltaic and no mains power, 5kw can work off-grid to a certain extent. However, when the load power is greater than the photovoltaic power, the inverter will stop working. This situation is suitable for loads that can change with the input. , such as electric water heaters, etc., or situations where the photovoltaic power is much larger than the load power.
- When the system has no photovoltaic and commercial power, 5kw can be bypassed with load, and the dormant lithium battery can be charged and activated.
In addition, 5kw has also developed two practical functions, the scheduled charging function and the scheduled output function. Timing charging function: Customers can customize the charging time period of the mains power and limit the use of grid charging during peak electricity price periods, which can reduce electricity bills; Timing output function: Customers can set a timing output so that the inverter automatically shuts down during a certain period of time. Ensure to reduce the system’s own losses.
Scope of application:
This Lolsolar off-grid machine supports up to 6 units in parallel and can build a 30kW single-phase or three-phase system. It is suitable for small commercial power stations that have self-consumption of surplus electricity that cannot be connected to the Internet, and the load does not exceed 30kW, and the load power and photovoltaic power generation are basically synchronized. Application occasions.
Not suitable for occasions: where the equipment load is greater than 30kW and where photovoltaic power generation and equipment power consumption are out of sync.
Off-grid solar power generation systems are not restricted by geography and do not rely on the power grid. They can be installed and used wherever there is sunlight. It is a good choice to install one in areas without electricity or frequent power outages.
Off-grid solar power generation systems need to be equipped with off-grid inverters to convert the DC power from the solar power generation system into AC power for daily AC appliances. Lolsolar Off-grid inverters need to be equipped with batteries to start and operate normally. These energy storage batteries are expensive and have short lifespan, which increases the initial investment cost of the system. Therefore, the application of off-grid solar power generation systems is also limited.
Does the lolsolar off-grid inverter need to be equipped with a battery? The answer is not necessarily
In addition to the basic functions of conventional off-grid inverters, users can also choose a battery-free operating mode. In battery-free mode, the off-grid inverter automatically turns on when powered by solar energy. For areas with developed power grids but expensive electricity bills, or areas that only need electricity during the day, or areas without electricity, the inverter always uses solar power to reduce the pressure on the grid. , reduce electricity costs and save battery costs.
