In this episode, Brad, Brian and Paul dig into the latest grid-tied PV plus battery applications like self-consumption and TOU optimization as well as a few questions about battery backup.
Questions addressed in this episode:
Is it possible to build a system that utilizes High-Power batteries (i.e. Powerwall) for large instantaneous loads alongside an Aquion Battery system for sustained energy usage?
How does monitoring works for battery systems?
Are you seeing people in the US wanting battery systems more for self-consumption or for both self and battery backup”
How do you do a grid-tie battery backup system using microinverters?
Are any of the back-up inverter electronics rated to -40C ?
Is there an automatic transfer switch we recommend for PV backup systems?
If a grid tie system is retro fitted battery back-up to operate during a power outage, what would happen to power produced that is not consumed by the load?
Is there no way to do the SolarEdge/Tesla setup without installing a separate load center for protected loads?
Do you have any tools that would be able to calculate or help estimate system size and storage needed for off grid applications, such as tiny home or van living?
What’s your take on simply using a generator with a stored tank of propane in place of batteries for customers that want cost-effective backup (regardless of whether or not they have PV)?
What’s your take on the Enphase “AC battery” that’s due out later this year?
Any idea how the Enphase batteries charge from the grid? I understand there is a S280 under the hood, but how can this charge the battery?
