This series presents advanced Solar Storage Inverters (spanning multiple series including SAL and GTR models, with power options ranging from 3K up to 15K). These intelligent energy management systems expertly integrate photovoltaic (PV) charging, sophisticated battery energy storage management, and ultra-stable pure sine wave AC output into a single unified solution, encased in precisely engineered, thermally optimized chassis that feel remarkably solid to the touch. They are meticulously engineered to provide an efficient, uninterrupted, and highly cost-effective power supply across a broad variety of demanding setups, including residential houses, farms, rural areas, islands, pastures, and telecommunication base stations. By mitigating grid instability and maximizing renewable energy utilization, these systems empower facility managers and system integrators to drastically reduce long-term operational expenditures while maintaining peak electrical performance round the clock.
Digital Signal Control: Adopts high-performance DSP (Digital Signal Processor) or dual DSP full digital control modes to guarantee precise operation and maximum system stability. By incorporating internationally recognized, top-tier IGBT modules and ultra-fast microprocessors, the internal architecture ensures exceptional thermal management and electrical resilience. This premium component selection guarantees that the equipment maintains extreme stability and an extended operational lifespan even under maximum load conditions or within severe ambient environments.
High-Precision MPPT: Features a built-in, highly accurate Maximum Power Point Tracking (MPPT) controller to maximize solar panel utilization. Higher-capacity models include dual independent MPPT inputs to achieve up to double the PV input power capacity. This intelligent tracking mechanism rapidly adapts to fluctuating sunlight conditions, capturing every available watt of solar energy, thereby accelerating the return on investment for large-scale energy deployments.
Pure Sine Wave Output: Delivers precision-engineered pure sine wave AC electricity with a peak efficiency of up to 93%, providing reliable defense for sensitive electrical loads. The superior surge resistance and pristine waveform perfectly accommodate heavy-duty and inductive loads, including agricultural water pumps, industrial motors, commercial compressors, and other sensitive electronic equipment, ensuring they run cooler and quieter without harmonic distortion.
Hybrid Power Blending: If solar generation is insufficient, the system dynamically combines PV power, the utility grid, and energy storage batteries together to continuously power the connected load. This multi-source synchronization happens in milliseconds, ensuring that critical operations experience zero flickering or power interruption during energy transitions.
Flexible Auxiliary Sources: Supports fluid selection between the public utility grid or diesel/gasoline generators as a backup input. The intelligent detection circuit automatically stabilizes erratic generator voltage, delivering a clean, filtered power feed to the end devices and protecting them from mechanical wear.
Configurable Input Priorities: Grid and PV power supply priorities can be customized manually to match regional grid stability or electrical pricing structures. Facility operators can program the exact sequence of energy draw, optimizing consumption based on real-time availability and local utility constraints.
Time-of-Use Economic Modes: Offers smart programmable scheduling for battery charging and discharging periods, allowing users to reduce electricity bills by shifting demand. By storing energy during off-peak hours and discharging during expensive peak tariff periods, the system actively generates financial savings day after day.
Multi-Battery Protocols: Broadly compatible with both Lithium-ion and Lead-acid battery chemistries, featuring integrated battery balanced-charging modes. Advanced models directly support lithium battery BMS communications via RS485/CAN interfaces. This deep integration allows for precise cell voltage monitoring and state-of-charge tracking, preventing premature battery degradation and maximizing the storage array's lifecycle.
Battery-Free Operation & Anti-Backflow: Specific variations (such as the SAL 6K Pro) feature a specialized anti-backflow grid connection capability and fully support running without attached batteries by blending solar and mains power. This unique architectural advantage drastically lowers the initial deployment capital for sites that only require daytime power augmentation, offering unparalleled design flexibility.
Eco Mode Operation: Built-in power-saving functions significantly reduce system idle power draw and minimize no-load losses. When the connected load drops below a predefined threshold, the inverter enters a dormant state, emitting a faint, reassuring hum only when actively surging power, thereby conserving stored energy for when it is truly needed.
Scalable Multi-Unit Paralleling: Supports the parallel coupling of up to 6 units simultaneously, letting users construct powerful single-phase or three-phase four-wire electrical generation systems. This modular scalability ensures that as energy demands grow, the infrastructure can expand linearly without requiring a complete system overhaul.
Advanced Electrical Protections: Comes equipped with multi-stage 360-degree all-round protection layouts. High-tier variants integrate ISO array insulation resistance tracking on the PV lines alongside GFCI ground fault leakage monitoring on the AC end to maximize occupational safety. These rigorous safeguards protect both the hardware investment and the personnel operating the microgrid.
Smart Air Cooling: Uses specialized temperature-responsive, intelligent adjustable-speed cooling fans to handle heat dissipation efficiently and boost the system's operational life span. The precisely engineered airflow channels expel excess thermal buildup quietly, ensuring internal components remain within their optimal temperature envelope.
Remote Monitoring Support & Intuitive HMI: Features optional Wi-Fi or GPRS expansion cards, enabling users to easily track their energy systems via remote tracking platforms. Furthermore, the front panel is equipped with a large, high-definition LCD/LED intelligent display. This multi-language interface provides highly intuitive operation, making real-time system data, charge/discharge status, and instant fault warnings visible at a single glance.
Indoor Application Enclosures: Standard models feature a lightweight, compact physical body built around an IP21 protection standard. The sleek, powder-coated metallic finish not only looks professional in utility rooms but also resists everyday scuffs and environmental wear.
Heavy-Duty Outdoor Enclosures: Select outdoor models (such as the GTR 6K) boast a rugged, heavy-duty IP65 ingress protection degree, making them completely prepared to withstand harsh and demanding outdoor environments. Sealed against fine dust intrusion and powerful water jets, these heavy-duty casings ensure relentless performance whether installed on a humid tropical island or a dusty agricultural farm.

The solar storage inverter converts electricity generated by PV panels into usable AC power while managing energy flow between the solar array, battery bank, utility grid and connected loads.
During periods of strong solar generation, the inverter prioritizes PV power for the connected loads and can direct surplus energy to the battery for storage. When solar production is insufficient, stored battery energy or utility grid power can be used to maintain a stable power supply.
Users can configure different power priorities according to electricity demand, grid availability and battery charging requirements. Selected models also support generator input, battery-free operation and programmable charging and discharging schedules.
Multiple power ratings allow customers to select an inverter according to load demand and system capacity.
We support customized inverter configurations, communication interfaces and energy storage system integration according to project requirements.
