What is the best battery to use with an inverter?

There are many kinds of batteries in the market, and customers always ask CARSPA sales: what battery is the best for the inverter?

Generally, batteries used with inverters include two types: solid-state and liquid lead-acid. Solids contain lithium and GEL batteries, liquids contain AGM/flood/calcium/lead-acid batteries.

At present, lithium batteries are the best batteries for inverters in solar systems, automotive applications, power tools, etc., in terms of service life and battery energy. Liquid batteries are cheaper and more economical, but have a much shorter lifespan than solid-state batteries.

Especially for grid-connected energy storage systems, customers use 48Vdc or even 200Vdc lithium battery systems. For cars such as RVs and four-wheel drive vehicles, lithium batteries are usually 12VDC or 24VDC, with capacities of 100Ah, 120Ah, 150Ah, 200Ah and 300Ah, which are sufficient for vehicles.

3, 4 years ago, solar system installers used lead acid/gel batteries to store solar energy, they were heavy and bulky enough to fit on a shelf, lead acid batteries were half the price of solid batteries, and lasted 1/2 3 or even solid-state 1/4, because there is no starting current limit, so there is no problem with the AC load working on the inverter, and the lithium battery may have a maximum output current limit, and the AC load will be locked when working at high power. Inductive loads, such as micro fans, water pumps, motors.

Therefore, the best battery for your inverter depends on your budget, lifespan plan, AC load type.
