Which battery for which inverter?
The compatibility between a battery and an inverter depends on the voltage and capacity of the battery as well as the specifications of the inverter. Generally, a 12V battery is used with a 12V inverter, a 24V battery with a 24V inverter, etc. Battery capacity, measured in amp-hours (Ah), should be sufficient to provide the necessary power for the duration you need. For example, a 100 Ah battery is typically paired with inverters for low to medium power needs, while larger systems may use multiple batteries in series or parallel to match higher voltage inverters (48V or more) and provide greater storage capacity.
Which inverter on which battery?
The inverter you choose should match the voltage of your battery system. For example, if you have a 24V battery bank, you need a 24V inverter. The power rating of the inverter should also be greater than the total power of the devices you plan to power simultaneously to avoid overloading the system. For example, if you plan to run appliances totaling 2,000 watts, you should select an inverter with a capacity of at least 2,500 watts to provide a margin of safety. Additionally, if you are using a solar power system, the inverter should be compatible with solar charge controllers and designed to integrate with your specific battery type (e.g. lead-acid, lithium-ion).
Can a battery be connected to any inverter?
Not all batteries can be connected to an inverter; the inverter and battery must be compatible in terms of voltage, chemical composition and intended use. Using an incompatible battery may result in inefficient performance, safety hazards, or even damage to the inverter and battery. For example, connecting a 12V battery to a 24V inverter may cause the inverter to malfunction or fail. It is crucial to ensure that the inverter input voltage matches the battery output voltage and that the battery chemistry (e.g. lead-acid, lithium-ion) is supported by the charging and discharging profiles of the inverter.
For a home battery system, you need an inverter compatible with the voltage and capacity of the battery, typically designed for residential energy storage. Hybrid inverters are a popular choice because they can handle both solar power and battery storage, providing an integrated solution for homes with solar panels. These inverters should have features such as battery management, seamless switching to backup power in the event of an outage, and the ability to prioritize power consumption from solar panels, the grid, or batteries. Brands like Tesla, SolarEdge and SMA offer inverters specifically designed for home battery systems, often paired with lithium-ion batteries for efficiency and longevity.
The voltage required to start an inverter depends on the design of the inverter and the system in which it is integrated. Most small and medium-sized residential inverters start with a battery voltage of 12V, 24V, or 48V, depending on the system configuration. For example, a 12V inverter will start with a 12V battery bank. Larger or more sophisticated inverters used in off-grid or grid-connected solar systems may require higher starting voltages, typically 48V or higher. The starting voltage must always match the nominal voltage of the battery bank to ensure proper operation and avoid damage to the system.
