The Sol-Ark Whole Home 15K-2P is a residential all-in-one hybrid inverter designed to back up an entire home. With 200A of grid pass-through it can be installed ahead of your main panel, so every circuit stays powered during an outage, not just a critical-loads subpanel. It integrates the solar inverter, three MPPT charge controllers, a 48V battery inverter/charger and an automatic transfer switch in one outdoor-rated enclosure.
The 15K-2P keeps producing power through prolonged grid outages, manages your battery and grid use around time-of-use rates, and scales up to 12 units in parallel as your needs grow.

EMP Hardened Option
Select EMP Hardened: Yes for Sol-Ark's 2X military-grade EMP option, a factory-hardened 15K-2P designed to keep operating after electromagnetic pulse events such as severe solar storms and lightning strikes. Sol-Ark states the EMP-hardened 15K-2P meets and exceeds the MIL-STD-461G standard; the test report is linked below. Ratings and specifications are otherwise the same as the standard model.
