We should not overemphasize the need for batteries in off-grid solar systems. For our solar system, we should charge your battery during the day through solar panels and discharge deeply after sunset. But the question is: how do we choose a battery? Here are some tips that may help you choose a battery.
An off-grid solar system, also known as an independent photovoltaic system, is a standalone power generation system that does not rely on the power grid. The off-grid solar system is mainly composed of components such as solar panels, batteries, solar controllers, and inverters. The DC generated by the solar panel directly flows into the battery and is stored. When DC power is needed to supply AC loads, the DC power in the battery is converted into AC output by the inverter, which is a repeated charge and discharge cycle. Commercial off-grid solar systems can be installed and used where there is sunlight, so off-grid solar systems are very suitable for home use, areas without power grids, fishing boats, outdoor breeding bases, etc. In addition, it can also be used in areas where there is frequent power outages as emergency power generation equipment.
When selecting batteries, it is important to match the rated voltage with the battery charger and off-grid inverter.
Pay attention to the capacity in Ah (ampere-hour).
You should choose the highest possible efficiency. If you don't get a battery that is very efficient, you may have to compensate for its inefficiency with a larger solar panel. Therefore, this feature is very important.
The lifespan of a good complete off-grid solar system battery is usually about 3-4 years. Anything below this value may put you at a disadvantage of incurring additional costs, so it is important to use the equipment correctly.
Off-grid solar power generation systems actually convert solar energy into electrical energy through solar panels under lighting conditions, supply loads with DC power through solar charge and discharge controllers, and charge the battery group. In rainy weather or in the absence of sunlight, the DC load is supplied by the battery group through the solar charge and discharge controller, and the battery group also directly supplies the independent inverter with power, which is inverted into AC power and supplied to AC loads.
The design of Anern products is based on customer needs and industry development, guided by product technology research, and integrated with advanced design concepts.
We use SMD5730, EPISTAR and LG 3030 LED chips, with high light efficiency, low power consumption, wide luminous Angle and other characteristics.
For samples, full by T/T in advance; for bulk order, 30% deposit by TT in advance, balance by TT before shipment. The L/C is acceptable for big order. It can be negotiable.
Anern provides on-grid solar systems, off-grid solar systems, hybrid solar systems, and integrated solar energy storage systems that combine solar panels, inverters, lithium batteries, and system accessories.
