I wanted to get thoughts on adding batteries to my newly installed solar PV system. I am pretty new to this technology....
My understanding (from installer/engineer) is that when there is a power outage (grid) I lose the ability to use the energy created by my panels. I was going to install a portable gas generator as a backup however he also mentioned using a small battery pack. He said the solar system needs to send the power somewhere (for me to use it) but if the grid is down, so am I. He said I can install a small battery system so that the solar system can send the power to it, but then I can also use the power during the day. At night I guess I would use the batteries that may drain rather quickly depending on size. He said I would need an inverter however to convert the AC back to DC (my PC systems uses micro inverters on the roof). Apparently there is no risk to overloading the batteries either <?>
I suspect the cost would vary by the batteries (size, number, etc.) and the inverter may be expensive too.
I would not want a large battery system... maybe just something so that I can use the energy from the panels during the day (given sunlight), and maybe just use a generator at night, if needed.
Any thoughts, insights, are appreciated...
Wonder if this is something I (or electrician) can easily do.....?
