High-Efficiency Solar Solution
Maximize your solar energy harvest with the 4DTL2-G3, a premium single-phase string inverter designed specifically for modern residential PV systems. As a trusted wholesale supplier, DTSolarPower provides this high-performance unit to help EPC contractors and solar installers deliver reliable, grid-compliant energy solutions to their clients.
Technical Excellence & Performance
The SOFAR 4KTL2-G3 is engineered for efficiency and durability. With a maximum efficiency of 97.7% and a European weighted efficiency of 97.2%, it ensures minimal energy loss during the DC-to-AC conversion process.
- Optimized Energy Harvest: The ultra-low start-up voltage of 70V allows the system to begin generating power earlier in the morning and continue later into the evening compared to standard inverters.
- High-Current Compatibility: Featuring a max input MPPT current of 15A, this inverter is fully compatible with the latest generation of high-power, large-format solar modules.
- Flexible Design: The single MPPT tracker and transformerless topology make it a lightweight, compact choice for straightforward domestic installations.

FAQ
Q: How does the low start-up voltage benefit the end-user?
A: The start-up voltage is only 70V, which means the system begins generating power earlier in the morning and shuts down later in the evening, increasing the total daily yield.
Q: What level of surge protection is included?
A: The inverter features built-in Type III SPD (Surge Protective Device) for both the PV (DC) and AC sides, protecting the internal circuitry from voltage spikes.
Q: Is this inverter compliant with local grid standards?
A: We provide full certification for major markets, including EN50549, VDE-AR-N 4105, and IEC62109, ensuring seamless grid connection and safety.
Q: What is the IP rating for outdoor installation?
A: The series is IP65 rated, making it completely dust-tight and protected against water jets, suitable for harsh outdoor environments.
Q: Are you able to provide technical support for system sizing?
A: Absolutely. Our engineering team can assist with string design and system sizing to ensure the SOFAR 4KTL2-G3 is perfectly matched to your specific PV module configuration.
