Can batteries be retrofitted to an existing solar system?

Yes, In the last year we have seen the introduction of 2 systems that are AC coupled, this means that they run off AC power and do not require a DC supply to the batteries to make then produce power. In basic terms, most on systems had simple inverters that didn’t have the functionality to charge a battery and the batteries that were being installed were not smart enough to work by them self. This caused issues and extra components to retrofit your solar battery, this is still an option available but now with the AC coupled systems are a lot easier and additional components are not as required. The two companies that have smarter batteries with their own inbuilt battery management systems are Enphase and Tesla. This new technology will change the battery sector in the market. Not there are still a lot of other options available and there is no one size fits all in this area of the industry.
