FranklinWH APRS-10K15V1-US aPower S Inverter/Battery 10KW/15KWH

FranklinWH aPower S (APRS-10K15V1-US) – 15kWh 10kW All-in-One Hybrid Solar Battery Storage SystemThe FranklinWH aPower S (APRS-10K15V1-US) is a next-generation all-in-one hybrid solar battery storage system that combines a high-capacity 15 kWh LFP battery with a built-in hybrid inverter. Designed for direct DC connection to solar PV panels, it delivers maximum energy capture, simplified installation, and powerful whole-home backup in a single sleek unit.Unlike traditional AC-coupled batteries, the aPower S supports direct solar integration through four built-in MPPT trackers. This DC-coupled design reduces conversion losses, boosts overall system efficiency, and eliminates the need for a separate string inverter in many installations. It is also fully compatible with the FranklinWH aPower 2, allowing flexible AC-coupled expansion for growing energy needs.Key Features & Benefits Direct DC Solar Connection — Four high-current MPPT trackers (15 A each) support up to 20 kW solar STC input, maximizing energy harvest from modern high-output PV arrays. Powerful Whole-Home Backup — Delivers 10 kW continuous output (battery only) or up to 11.5 kW with PV input, with 15 kW peak for 10 seconds. Capable of starting heavy 240V loads like a 5-ton air conditioner. Simplified & Cost-Effective Installation — Front-wiring design and all-in-one architecture reduce conduit runs, components, and labor time compared to separate inverter battery setups. High Efficiency & Longevity — 90.5% round-trip efficiency (solar-battery-load) and up to 97.5% solar-to-home/grid CEC efficiency. Safe LFP chemistry with a 15-year or 60 MWh throughput warranty (to 70% SOH). Durable Outdoor/Indoor Rating — IP67 protection, built-in heating blanket for cold climates, and quiet operation (~30 dBA typical). Operates reliably from -4°F to 122°F (-20°C to 50°C), with derating up to 131°F. Smart Energy Management — Pairs with the FranklinWH app for real-time monitoring, time-of-use optimization, emergency backup modes, revenue-grade metering, and advanced safety features including AFCI and isolation monitoring.Technical Specifications Usable Energy Capacity: 15 kWh per unit (scalable up to 15 units / 225 kWh total per aGate) Power Output: 10 kW continuous (battery), 11.5 kW continuous (with PV), 15 kW peak (10 seconds) Charge Power: Up to 8 kW Solar Input: 4 MPPTs, max 20 kW STC, MPPT voltage 90–480 Vdc (max 600 Vdc) AC Output: 120/240 V split-phase (or 120/208 V), 60 Hz, hybrid-coupled Dimensions (H × W × D): 45.2 in × 29.5 in × 11.8 in (1149 × 750 × 300 mm) Weight: Approximately 365–388 lbs (166–176 kg) Enclosure: Type 3R / IP67, natural air cooling, wall or floor mount Warranty: 15 years or 60 MWh aggregate throughputWho It’s ForThe FranklinWH aPower S is ideal for homeowners seeking a high-performance 15kWh home battery with built-in inverter for new solar installations, retrofits, or whole-home backup.
