Fox ESS · 13.98 kWh · HV stack, 1 master + 2 slaves
Fox ESS EQ4800-L3 13.98kWh HV battery stack
This is the EQ4800-L3: a pre-configured Fox ESS high-voltage stack of one master and two slave modules, 13.98kWh in total. On a new install for a typical family home it puts the whole battery on one order line instead of three.
Delivery in 3–5 working days (estimate). The dispatch clock starts at cleared payment.
Description
Ordering the stack as a bundle removes the classic picking error, a master short or a slave over, because the L3 part number always means one master and two slaves. That suits firms quoting new installs at pace: the estimator writes one code, the warehouse pulls one bundle, the van carries a matched set. It sits in the middle of the EQ4800 bundle range, so there is headroom above it if the survey changes, and smaller options below if it does not. Trade pricing holds at any quantity from UK stock.

What it pairs with
Within the Fox ESS range it belongs with the single-phase hybrid inverters, the H1 Gen 2 and K series units, at a family level. Capacity can grow later by adding EQ4800 slave modules (FE-HV-EQS-4800) to the master. Module counts and firmware revisions matter in EQ stacking, so verify the combination against Fox's current stacking list before final design.
A single-phase listing, supplied as a fixed one-master, two-slave configuration. Growing beyond 13.98kWh means adding further EQ slave modules. For anything this page can't settle, ask the trade desk before ordering or consult a competent installer.
