Installing a battery backup system while using microinverters is not only possible, it can make a lot of sense in several scenarios, including areas with rolling power outages, high electrical rates, or if the end user would like to install a system over time, spreading out the cost. Install a PV system using microinverters, and in time a battery backup system can be added. But to do so, there are real considerations to take into account.
How will the microinverters and the batteries communicate? Can the system owner monitor both of the PV output and the battery status in one data manager (web or logger)? What considerations need to be taken into account when installing the initial PV with microinverter system for future battery backup? Are there additional electrical code concerns with battery backup?
Using the new, Magnum MicroGT 500 and a Magnum MS-PAE Inverter/Charger system as the example, we will cover all of these questions, and more. You will leave with a real understanding of how these two systems work together successfully.
Alan Santos-Buch, from Sensata Technologies, will cover:
- Components necessary for a microinverter with battery backup system
- What should you look for in a communications system between microinverters and battery backup
- Power flow considerations when utility power is present and when it isn’t
- Basic installation overview
