How to choose a solar battery for home
A solar battery stores the energy your panels produce during the day so you can use it at night or during a power cut. Choosing one is not only about the biggest number on the label. The battery has to suit your solar inverter or charge controller, the load you want to run, and the space you have. This guide walks through the main decisions for homes and small shops in Visakhapatnam.
Start with what you want to run
List the appliances that should keep working from the battery: lights, fans, a refrigerator, a television, a computer, a water pump. Note how many hours you want them to run without grid power. This gives you a rough idea of how much stored energy you need, which decides the battery capacity and how many batteries the system uses.
If you are planning a new solar setup rather than replacing a battery, it is worth thinking about the whole system: panels, the solar inverter or PCU, and the batteries together. Our article on power cut backup options for homes and shops compares the main choices.
Match the battery to your solar inverter
Every solar inverter and charge controller works with a set battery voltage, and many have a recommended capacity range. Before you choose a battery, check:
- the system voltage (for example 12 V, 24 V or 48 V), which decides how many batteries are connected together
- the battery types the inverter supports
- the charging current the inverter can supply, which affects how large a battery it can charge properly
If you are unsure, send us the solar inverter's brand and model on WhatsApp and we will check what suits it.
Solar battery types
- Tubular solar batteries are a common choice for daily charging and discharging. They are tall and need water topping up and ventilation.
- Flat plate batteries are lighter and usually more compact, and suit smaller loads.
- Sealed or maintenance-free batteries need no water topping, which helps where the battery is hard to reach, but they must be charged correctly.
The right type depends on your daily use, budget and where the battery will sit. Our solar battery range and the brand lists for Exide Solar and Luminous show what is available.
Space, heat and care
Solar batteries in Visakhapatnam face heat and humidity. Place them in a shaded, ventilated area off the floor, away from direct sunlight and away from sleeping areas. Keep terminals clean and, for tubular batteries, check the water level regularly and top up only with distilled water. Avoid draining the battery completely every night, as deep discharges shorten its life.
Replacing a solar battery
If your solar system gives less backup than before, the batteries may be ageing, but check the panels, wiring and inverter settings too. When replacement is due, all batteries in a series bank are usually replaced together, because mixing old and new batteries shortens the life of the new ones.
