II. Six Core Product Advantages
-
Super‑high power conversion efficiency with dual independent MPPT channelsEquipped with dual independent MPPT controllers achieving an MPPT tracking efficiency up to 99.9%. The maximum PV input current per channel is 22 A, bringing a combined PV access capacity of 11 kW for two channels. Compatible with high‑power PV modules, it maximizes solar‑energy utilization even on complex rooftops under partial‑shading conditions. The peak battery‑to‑AC inversion efficiency reaches 92%.
-
All‑in‑one integrated design with large charging currentThree charging channels are integrated for PV, utility mains and generators. The maximum mixed charging current hits 200 A for the 10 kW model and 180 A for the 8 kW model for fast energy storage. It natively supports lithium‑ion‑battery BMS communication linkage and features exclusive dual‑activation protection for lithium‑ion‑battery BMS, compatible with lithium‑ion and lead‑acid batteries.
-
Robust & stable output for heavy‑duty motor loadsIt outputs standard pure‑sine‑wave AC power with clean waveforms that protect household appliances. The 10 kW model delivers 10 000 W rated power and 20 000 W peak power, capable of driving 6‑HP high‑power motors, air‑conditioners, water pumps and power tools. Single‑phase output is available; multi‑unit parallel connection enables three‑phase power expansion. Built‑in bypass power supply ensures seamless switch‑over and uninterrupted power for loads during grid outages.
-
Intelligent time‑of‑use tariff control for energy‑saving & cost reductionA built‑in time‑of‑use scheduling program automatically triggers off‑peak‑period charging and on‑peak‑period discharging to cut electricity expenses for households and commercial‑industrial users. Battery‑free no‑load operation is supported; loads can be powered directly by PV or utility mains without energy‑storage batteries for highly flexible operation modes.
-
Comprehensive safety protection & multiple‑country authoritative certificationsDual‑layer hardware‑and‑software multi‑protection covers over‑voltage, under‑voltage, over‑current, overload, short‑circuit and over‑temperature faults. The unit complies with IEC62109 international PV safety standards, EMC requirements under EN standards, FCC and RoHS environmental certifications. With IP20 indoor protection rating and built‑in thermostatically controlled fans, its operating noise stays below 60 dB.
-
Easy installation & O&M with intelligent remote monitoringIndustrial minimalist appearance with a lightweight wall‑mounted body. Dimensions: 620 × 445 × 130 mm; weight: only 27 kg. Standard communication interfaces include RS485, CAN, USB and dry contacts. Optional Wi‑Fi/GPRS modules enable mobile‑APP remote monitoring and remote‑parameter debugging. Up to 6 units can be connected in parallel for on‑demand power‑capacity expansion.

IV. Four Typical Application Scenarios (copy‑ready for image captions)
Scenario 1: PV‑Storage for Villas / Private Residences (Primary Application)
Suitable for rooftop PV systems on urban‑rural self‑built houses and detached villas. On‑site power consumption during daytime; surplus power stored in batteries for off‑grid power supply at night. Automatic time‑of‑use tariff scheduling reduces power costs for home air‑conditioners, water heaters and EV chargers. Automatic switch‑over to backup power during blackouts ensures continuous operation for refrigerators, lighting and surveillance devices.
Scenario 2: Small Retail Stores / Workshops / Micro Commercial‑Industrial Premises
Ideal for convenience stores, processing plants, agricultural workshops and small offices. Energy‑storage peak‑shaving & valley‑filling mitigates high‑power‑load peaks of water pumps, cutting machines and refrigeration equipment to reduce expensive peak‑time electricity bills. It serves as an uninterruptible backup power source for regions with unstable grids and frequent blackouts to avoid production losses caused by equipment shutdown. Multi‑unit parallel expansion meets high‑power commercial‑load demands.
Scenario 3: Remote Off‑grid Areas (Islands, Mountainous Regions, Farms, Border Outposts)
For rural locations with no or weak public‑grid coverage, aquaculture farms, field base stations and border posts. It delivers fully independent power supply from PV plus energy‑storage, supplemented by generators. Free from utility‑grid reliance, it stably powers lighting, irrigation equipment, surveillance systems and household appliances, solving power‑supply challenges in remote territories.
Scenario 4: Distributed PV‑Storage‑Charging Integrated Supporting System
Supporting system for home EV chargers and small‑scale PV charging stations. Solar energy is stored during daytime to charge new‑energy vehicles at night for self‑sufficient clean‑energy utilization. It supports micro‑grid construction and bidirectional complementation with utility mains to build small‑scale zero‑carbon energy systems.
