The SOFAR HYD KTL-3PH is a three-phase hybrid inverter designed for residential and small commercial solar systems. With its off-grid functionality, the unit can deliver power even during outages, ensuring energy independence when needed.
Available in models from 5kW to 20kW, it integrates solar, grid and battery power to provide an efficient and stable energy supply.
These offer dual MPPT tracking for flexible solar array layouts and support up to two battery inputs on 10kW models up. Whether installed alone or as part of a parallel system, the HYD series makes energy storage scalable and adaptable. It's fully digital control improves system precision while maintaining a compact footprint suitable for wall-mount installations.
Main Features
Off-grid capability: Delivers backup power with fast switching (<10ms), supporting unbalanced loads across three phases. Dual MPPT inputs: Allows two separate solar array configurations for more design flexibility and better yield. Battery-ready design: Supports two battery inputs with lithium-ion or lead-acid compatibility, plus smart BMS communication. Parallel support: Multiple inverters can work together, making system expansion easier and more efficient. Digital control system: Ensures higher accuracy and better energy management in both on-grid and off-grid scenarios.
Certifications: IEC, EN, AS/NZS standards for safety and grid compliance
Pain Points Addressed:
Power outages: Frequent grid disruptions can interrupt home or business operations. The HYD inverter’s off-grid functionality provides a reliable backup power source.
System inflexibility: Many solar inverters don’t scale well with future expansions. This model supports parallel operation and on 10-20kW models, multiple battery inputs for easier upgrades.
Battery compatibility issues: Some systems are locked into one battery brand or type. The HYD series supports both lithium-ion and lead-acid batteries, enhancing versatility.
Use Cases:
Residential homes: Ideal for homeowners with 3 phase power requirements seeking a hybrid solution with battery storage for backup during blackouts, or peak shaving during high-tariff times.
Small commercial buildings: Supports balanced or unbalanced loads across three phases, making it suitable for small offices or retail spaces needing reliable uptime.
Off-grid or remote areas: Enables energy independence in locations with unreliable or no grid access, especially when paired with sufficient battery storage.
System upgrades: Existing solar users wanting to add storage can integrate this inverter without overhauling their entire setup, thanks to its modular design.
New solar + battery installations: A strong all-in-one choice for new builds looking to combine solar generation, battery storage, and smart grid interaction in one unit.
Slow response to power loss: Traditional systems often have a delay in switching to backup power. This inverter responds in under 10 milliseconds, reducing downtime.

Important Disclaimer: Installation of Hardwired Electrical Products in Australia
Please read the following information, including the disclaimer at the bottom of this page; by purchasing from Buzz Energy Systems, you understand and acknowledge these terms.
When it comes to the installation of hardwired electrical products in Australia, it is important to be aware of the regulations and guidelines in place to ensure safety and compliance. As per the Electrical Safety Act, installations operating at ELV (Extra Low Voltage) levels of 120 VDC and below can be installed by individuals with the necessary knowledge and skills.
However, it is crucial to note that installations operating above ELV levels require the expertise of licensed electricians and experienced installers. Products falling under this category are not suitable for DIY (Do-It-Yourself) installation and must be handled by professionals. Attempting to install such products without the proper qualifications can not only compromise performance but also invalidate any manufacturer's warranties.
At Buzz Energy Systems, we recognise the importance of reliable and efficient installations that prioritise safety, performance and warranty compliance. Our team consists of qualified tradespeople and specialists who are equipped with the expertise required to handle complex electrical installations.
For installations that operate above ELV levels, we strongly advise against DIY installation. Instead, we recommend seeking professional assistance from licensed electricians and experienced installers to ensure the proper installation and optimal performance of such products.
When it comes to installing hardwired electrical products above ELV levels, rest assured that Buzz Energy Systems can provide the necessary qualified tradespeople and specialists. Our professional installation services guarantee compliance with regulations, the preservation of manufacturers warranties and most importantly, your safety.
Do not compromise on the installation of your hardwired electrical products. Trust Buzz Energy Systems for a professional and hassle-free experience. Contact us today for advice or to schedule your installation with our qualified team.
