Sol-Ark 15K + HomeGrid Stack'd Series LFP Bundle (SA-Limitless-15K, HG-4-STACK)

The Sol-Ark 15k is a great choice stackable solar/hybrid inverter! It's an all-in-one, pre-wired inverter with built-in charge controllers and many other built-in features fitted as standard. It is flexible, efficient, and affordable. Everything you need comes in one box, keeping your cost LOW and installation SIMPLE. 10-year Standard Warranty. This home battery is modular with 4.8 kWh increments, providing a capacity range of 9.6-38.4 kWh per Stack. This also allows for easy servicing and future expansion. With continuous output at up to 15 kW, and a surge of up to 24 kW for 10 seconds, true full-home backup is here. 1 Base, 4 4.8kWh Modules, total 19.2kWh Capacity. The new 15K inverter brings a new level of power and capability boasting 15,000W of continuous AC power, robust surge power (up to 24,000W (10 sec.)) as well as having three on-board MPPT controllers and two 200A battery breakers. The SA-Limitless-15K is also scalable in both 120V/240V split phase and 120V/208V 3 phase service voltages and can stack up to twelve (12) units in parallel.
