What are the battery requirements for the 4010ES, and what is the maximum battery size in each cabinet configuration?
0
The 4010ES requires a pair of 12V sealed lead-acid batteries wired in series for 24V backup power (Page 53) [1].
The maximum battery capacity that can be housed internally depends on the cabinet configuration:
-
One-bay cabinet: Supports up to 33 Ah batteries (Page 28) [1].
-
Two-bay cabinet: Supports up to 50 Ah batteries, which requires the 4100-0650 Battery Shelf (Page 53) [1].
The Main System Supply (MSS) charger is rated for a maximum capacity of 110 Ah for UL and 50 Ah for ULC (Page 21) [1].
Batteries exceeding internal cabinet limits must be installed in a remote battery cabinet within 20 feet of the panel using at least 12 AWG wire and a 4100-5128 Battery Distribution Terminal Block (Page 28) [1].
