Do I need a special inverter if I want to add batteries in the future?
Short answer: No, you don’t.
Longer answer:
If you’re planning to install solar now and add batteries later when the price is right, you’re making a smart move.
The great news is that you can add batteries to almost any standard grid connected inverter using a method called AC coupling. This means you don’t need to stress about finding or paying extra for a “battery ready” inverter upfront.
Some salespeople might push you toward a hybrid inverter, which uses DC coupling to connect batteries. While this might sound like a good idea, hybrid inverters are often more expensive and typically only compatible with a limited selection of battery brands and models. There’s a real chance those options won’t even be available when you’re ready to add storage in a few years.
With a standard inverter and AC coupling, you have the freedom to choose from a wide range of compatible batteries when the time comes. Better still, you’re not locking yourself into extra costs or limited compatibility today. In short, go with a quality inverter now, and enjoy the flexibility to upgrade with batteries later, without any regrets.
