We understand your off-grid solar system usage scenario very well, that is, the photovoltaic modules charge the battery during the day and power the load at night. Choosing a battery is indeed a science. I think the following aspects can help you:
- Voltage rating
When selecting a battery, the voltage rating needs to match the rating of the battery charger and off-grid inverter. - Capacity
Please pay attention to the battery capacity label, which should be in Ah (ampere/hour). - Efficiency
To maximize profits, it is recommended to choose battery products with higher energy efficiency. If you encounter non-high-efficiency products, you may need to increase investment in solar photovoltaic panels to balance the low efficiency. - Lifespan
A good quality battery has a service life of approximately 3 to 4 years, anything less than this may result in unnecessary expense. - Efficient and convenient
