Up to 9 units in parallel — scale from a single home to a small commercial block without swapping equipment. Single-phase, split-phase, and three-phase output all supported depending on model. Works at altitudes up to 5,000m.
MPPT tracking efficiency hits ≥99.9% across all GST and GSA series. DSP control with advanced algorithms means the inverter responds faster to changing sunlight conditions — less clipping, more yield, every day.
Grid-to-battery switching in under 10ms. Supports battery-free emergency output — the inverter can run directly from PV panels even with no battery connected. Four charging modes let your customer decide what the priority is: solar only, grid only, solar first, or hybrid.
APP cloud and host PC monitoring included. View real-time system data, modify parameters, and check fault types remotely — no on-site visit needed for most issues. Wi-Fi and 4G modules supported.
| Project type | Recommended series | Why |
|---|---|---|
Home with rooftop solar, grid-connected | GST Single-phase | 3.5–10kW, hybrid, 4 charging modes, APP monitoring |
Home or small business, three-phase grid | GST Three-phase | 8.5–12.5kW, three-phase output, up to 9 parallel |
US market / North America | US GST / Rock GST | 120/240VAC split-phase, US voltage standard |
Off-grid home, island, mountain area | GSA or GSI series | No grid required, MPPT controller built in, runs to 5,000m altitude |
Large off-grid system, three-phase load | GSI Three-phase | 10–400kVA, industrial-grade, 7" touchscreen, remote monitoring |
Industrial / commercial with battery storage | GPCS + GSI | PCS converter + off-grid inverter for peak shaving and backup |
Battery storage, or a Battery Energy Storage System (BESS), is a technology that captures energy from renewable sources like solar (PV) or the utility grid and stores it in a chemical form for later use. In modern systems, like the GSL-Easy Stack Series, this involves an integrated unit containing lithium batteries, a hybrid inverter, and an intelligent management system. These systems allow users to switch between multiple operating modes, such as PV priority, load priority, or grid-tie priority, to ensure power is available during outages or high-demand periods.
While specific pricing is customized based on project scale, the cost is primarily driven by capacity (kWh) and system integration. Investing in high-performance LiFePO4 (Lithium Iron Phosphate) systems is highly cost-effective due to:
Longevity: Systems designed for 10+ years of service with 5,000 to 6,000+ charge cycles.
Reduced Installation Costs: Modular “plug-and-play” designs (like the GSO Series) reduce on-site labor and assembly time.
Operational Savings: Features like peak shaving and valley filling allow the system to charge during low-cost off-peak hours and discharge during expensive peak hours, directly reducing electricity bills.
To calculate your requirements, you must determine your daily energy consumption in kWh and your desired autonomy (how long you want to run on battery alone). You can calculate individual module energy using the formula:
Nominal Voltage (V) x Nominal Capacity (Ah) = Total Energy (Wh)
Example: A standard GBP48-100 module (48V x 100Ah) provides 4.8kWh.
Scalability: For larger needs, systems like the GLV1 Series allow up to 8 clusters inparallel, reaching capacities over 30k Wh. Industrial cabinets can scale much higher,offering capacities from 15kWh up to 200 + kWh
Yes, particularly for users seeking energy independence and financial returns. Key benefits include:
High Efficiency: System conversion efficiency is typically ≥90%, ensuring minimal energy loss during the storage process.
Safety & Reliability: Modern units utilize Smart BMS (Battery Management Systems) with over-charge, over-discharge, and short-circuit protection.
Seamless Backup: With switching times as low as 10ms, the transition from grid to battery is unnoticeable, protecting sensitive electronics.
Environmental Impact: These systems use non-polluting materials free of heavy metals.
The “best” system depends on your specific installation environment:
For Space-Saving,Recommended Series:GBP-W (Power Wall),Key Advantage:Slim, wall-mounted design that minimizes footprint.
For All-in-One,Recommended Series:GSL-Easy Stack,Key Advantage:Integrated inverter and battery for easy “plug-and-play” setup.
For Scalable/Flexible,Recommended Series:GLV1 Series (Stackable),Key Advantage:Allows you to add modules as your energy needs grow.
For Portable/Flexible,Recommended Series:GBP-L (Wheel Type),Key Advantage:Equipped with a wheeled chassis for easy on-site movement.
While 1000mAh (1Ah) cells are typically used for small-scale applications like solar garden lights or portable electronics, professional Solar Battery Storage
Systems for homes and industry utilize high-capacity 3.2V LiFePO4 cells as their building blocks.
Cell Integration: These 3.2V cells are connected in series (e.g., 16S1P) to create the 51.2V modules used in residential storage.
Standard Capacities: Professional grade storage starts at 100Ah to 314Ah per cell to provide the energy density required for whole-home backup
