We're going to install a 20kW grid-tied pv system with the high voltage SMA battery backup. SMA has approved LG Chem and BYD batteries for its equipment.We have no experience with either battery and were wondering wrenches experiences or preferences with the two choices. Pricing and temperature requirements are about the same. One noticeable difference is that the LG is wall mounted and the BYD is stacked on the floor.
