The 48V Off Grid Solar Energy Storage Power System is not a standardized product, the same configuration may not be suitable for all users, but is designed and configured according to the user's usage, and the usage types are different in different places. In this regard, what kind of 48V Off Grid Solar Energy Storage Power System should I choose?

First, consider whether it is for pure lighting or for household appliances?

48V Off Grid Solar Energy Storage Power System can be divided into two types according to its functions, one is a home DC lighting system for lighting only; the other is a 220V AC output power generation system that can be used for both lighting and household appliances. The lighting system has simple functions and is also the most cost-effective power generation system, but it cannot be used for household appliances.

Second, is it better to choose a portable all-in-one machine or a combined one?

The portable all-in-one machine is also developed and designed for portability. It is easy to carry and requires no installation. It is very suitable for outdoor camping. However, due to its limited size, the storage capacity is small. The combined type requires simple installation and large storage capacity, which is both practical and affordable, because it is also more suitable for home users and outdoor residences.

The 48V Off Grid Solar Energy Storage Power System is mainly composed of solar cell modules, controllers, and batteries. To supply power to AC loads, an AC inverter needs to be configured. Independent photovoltaic systems can be divided into two categories: DC photovoltaic power generation systems and AC photovoltaic power generation systems. The characteristic of the battery-free DC photovoltaic power generation system is that the electrical load is a DC load, there is no requirement for the load usage time, and the load is mainly used during the day. The solar cell is directly connected to the electrical load. When there is sunlight, it generates electricity for the load to work, and when there is no sunlight, it stops working. The system does not require the use of a controller and there is no battery storage device. The advantage of the battery-free DC photovoltaic power generation system is that the loss caused by the energy passing through the controller and the storage and release of the battery is eliminated, and the solar energy utilization efficiency is improved.

Third, off-grid or grid-connected?

At present, there are two main types of Solar Energy Storage Power System: off-grid and grid-connected, and grid-connected is divided into two types with energy storage and without energy storage. The components of each type are different, the suitable places are different, and the most important thing is that the cost is very different. Generally speaking, the cost of an off-grid system is much higher than that of a grid-connected system, and a grid-connected system with energy storage devices is higher than a grid-connected system without energy storage devices. 48V Off Grid Solar Energy Storage Power System is suitable for use anywhere, and grid connection is only suitable for places where there is a public grid that can be integrated.

Fourth, about the size of the system capacity

The system capacity refers to the size of the 48V Off Grid Solar Energy Storage Power System, which directly determines the amount of electricity generated in a day. Usually, "W" is used to represent watts. Whether it is a grid-connected or off-grid energy storage system, the system capacity It refers to the number of solar panels installed. However, in the off-grid power generation system, some manufacturers use the output power of the inverter to represent the system capacity, which is an unprofessional representation method and should be paid attention to when purchasing.
