Model SA-15K-2P-N | 15kW | Split-Phase 120/240Vac | Grid-Tied & Off-Grid | 96.5% CEC | 48V Battery | 6 MPPT | Wi-Fi & LAN | 10-Year Warranty
The Sol-Ark SA-15K-2P-N is a premium 15kW all-in-one hybrid solar inverter engineered for both grid-tied and off-grid residential and light commercial applications. Delivering 12,000W of continuous reliable output power with a 96.5% CEC efficiency rating, this split-phase 120/240Vac inverter integrates six independent MPPT channels capable of accepting up to 19,500W of solar input — making it one of the highest solar-capacity residential hybrid inverters available. With a 5ms backup response time, support for both Lead-Acid and Lithium-Ion battery chemistries, 275A continuous battery charging, and integrated CanBus, RS485, Wi-Fi, and LAN communication interfaces, the SA-15K-2P-N is purpose-built to serve as the intelligent energy hub of a complete, fully managed solar-plus-storage system.
15kW Continuous Output — Grid-Tied & Off-Grid: The SA-15K-2P-N delivers 12,000W of reliable continuous output across all operating modes — grid-tied, off-grid, and hybrid — making it capable of powering whole-home loads in both utility-connected and fully islanded installations without compromise.
19.5kW Solar Input Across 6 Independent MPPTs: Six independent MPPT channels with a combined 19,500W solar input capacity allow strings on multiple roof orientations, tilt angles, or shading profiles to each operate at their individual optimal voltage — maximizing total energy harvest from complex multi-array configurations that a single or dual-MPPT inverter would compromise.
Universal Battery Chemistry Support: Native support for both Lead-Acid and Lithium-Ion battery systems — including integrated CanBus and RS485 interfaces for direct communication with major lithium battery brands — means the SA-15K-2P-N works with today's storage solutions and remains compatible with future battery upgrades without requiring an inverter replacement.
275A Continuous Battery Charging at 96.5% CEC Efficiency: A maximum continuous charging output of 275A at 48V ensures batteries are replenished at maximum speed during peak solar production. Combined with a 96.5% CEC efficiency rating, this inverter minimizes conversion losses across the full solar-to-battery-to-load energy chain — preserving more energy at every step.
5ms Ultra-Fast Backup Transfer: A 5-millisecond grid-to-backup transfer time is fast enough to prevent interruption of virtually all sensitive electronic equipment — computers, medical devices, NAS storage, and smart home systems — providing seamless, undetectable backup switching that is indistinguishable from normal grid operation for most connected loads.
Integrated Surge Protection & 10-Year Warranty: Built-in surge protection safeguards connected electronics against voltage spikes and transient overloads, while Sol-Ark's industry-leading 10-year standard warranty — one of the longest in the residential inverter market — reflects the company's confidence in long-term product reliability.
The Sol-Ark SA-15K-2P-N manages the complete energy flow of a solar-plus-storage system in a single all-in-one unit — from PV array DC input through battery charge management to split-phase AC output for home loads and grid interaction. Its intelligent control system continuously evaluates solar production, battery state, grid status, and load demand to route energy along the optimal path at every moment.
Transformerless DC-to-AC Conversion: The transformerless inverter topology converts DC power from both the solar array and battery bank directly to split-phase 120/240Vac output at up to 96.5% CEC efficiency — eliminating the weight, cost, and conversion losses of a traditional transformer while delivering cleaner, more stable AC output for sensitive home loads.
Seamless Power Source Transition (5ms): The inverter continuously monitors grid voltage and frequency. Upon detecting an outage or deviation outside acceptable limits, it transfers connected loads to battery-backed off-grid power within 5 milliseconds — faster than most UPS devices — maintaining uninterrupted supply to whole-home loads without any manual switching required.
Wi-Fi, LAN & Protocol-Based Monitoring: Built-in Wi-Fi and LAN connectivity enable real-time remote monitoring, control, and firmware updates via Sol-Ark's monitoring portal and third-party platforms. CanBus and RS485 interfaces enable direct digital communication with lithium battery management systems for state-of-charge accuracy, cell-level health monitoring, and coordinated charge/discharge management.
