Single Phase Solar Inverter
7~10.5 KTLM-G3 is a single-phase photovoltaic grid-connected inverter designed for household scenarios. The maximum current of a single channel supports 20A, which can be adapted to high-power components. The maximum efficiency reaches 98.1%, which can maximize the efficiency of solar energy. It is converted into alternating current for our use, so that living equipment can work normally, and it can allow customers to use clean energy and save electricity bills. It also has monitoring and protection functions, which can monitor the working status of solar panels and protect the panels from overcurrent, overvoltage and other problems.
Highlighted Features
Maximum Power Generation
Engineered for ultimate energy yield, this series boasts a 98.1% maximum efficiency. Combined with an ultra-low start-up voltage and a wide MPPT operating range, the system initiates generation earlier in the morning and shuts down later in the evening, capturing more daily sunlight to maximize overall power output.
High-Power Module Compatibility
Future-proof your solar arrays without technical bottlenecks. The hardware architecture is fully optimized and compatible with 500Wp+ PV modules. Its high input current capacity permits seamless integration with modern, large-format high-wattage panels without the risk of power throttling.
Fanless Quiet Operation
Designed to minimize operational wear and enhance residential comfort, the system relies entirely on natural cooling. With no mechanical fans to service or replace, it delivers exceptional thermal reliability, zero maintenance overhead, and an extremely low-noise performance ideal for quiet environments.

Application Scenarios
Large-Scale Residential Properties & Villas
Modern multi-story homes, luxury villas, and estates often have heavy energy loads driven by central air conditioning, electric vehicle (EV) charging stations, heat pumps, and smart home automation. This high-capacity series allows residential installers to deploy up to a 10.5kW system on a single phase.
Farms and Agricultural Facilities
Agricultural applications such as livestock sheds, automated greenhouses, solar-powered water pumping stations, and processing workshops frequently operate on single-phase utility lines due to their remote locations. Deploying this robust system allows farmers to utilize high-power 500Wp+ panels to offset daytime operational costs, run heavy machinery.
Small Commercial & Institutional Buildings
Small suburban office buildings, retail shops, medical clinics, and school facilities often require significant daytime power but are tied to standard local distribution networks. With the 3-MPPT architecture, independent tracking ensures that shading on one section of the roof does not degrade the performance of the entire system, guaranteeing steady, predictable energy yields throughout business hours.
FAQ
Q: With 3 MPPTs on a single-phase unit, what is the maximum current limit per MPPT, and can it handle unbalanced inputs?
A: The maximum input current is 20A for MPPT 1, and 16A each for MPPT 2 and MPPT 3. The system fully supports asymmetrical or unbalanced DC inputs across the three trackers.
Q: Is there a built-in DC switch, and does it meet international safety standards for rapid shutdown or isolation?
A: Yes, a physical, heavy-duty DC isolation switch is integrated into the bottom of the enclosure as a standard configuration. It provides safe manual isolation for maintenance work and complies with standard European and international PV safety regulations.
Q: Does the local commissioning app require an active cellular or internet connection to change grid parameters on-site?
A: No, local commissioning is executed via a direct Bluetooth connection between the installer's smartphone and the inverter.
Q: What level of granular data does the string fault monitoring provide? Can I see individual string voltages remotely?
A: Yes, the internal monitoring system tracks real-time voltage and current profiles for each of the 3 DC inputs. This data is transmitted back to the cloud portal, enabling your O&M team to diagnose string-level issues-such as a blown fuse or a localized shading problem.
Q: Which specific international grid-tied certifications and safety standards does this series currently carry?
A: This series is fully certified under major international standards, including IEC 62109-1/-2, IEC 62116, and IEC 61727. It carries CE marking and complies with various regional European and international grid codes.
