NorthStar Belt Driven Generator Head — 5,500 Surge Watts

Features include two 20 Amp 120V receptacles and a 20 Amp 240V locking plug receptacle. It uses NEMA 5-20R and NEMA L6-20R plugs, providing flexible connection options for common tools and appliances. Best for small to medium workshop projects or off-site job sites where reliable power is essential and where both 120V and 240V outlets are desired. A potential limitation is that this head requires a compatible engine to drive the belt system, so plan your setup accordingly.
NorthStar Belt-Driven Generator Head — 2,900 Surge Watts

Equipped with two 15 Amp 120V receptacles and two 15 Amp 240V receptacles, this head uses NEMA 5-15R and NEMA 6-15R plugs. It’s best for portable light-to-medium duty applications, such as roadside tools, small equipment, and field work where a compact, lower-output head is sufficient. A limitation to consider is its lower power ceiling compared to larger heads, which may restrict multi-tool simultaneous use.
NorthStar Belt Driven Generator Head — 10,000 Surge Watts

This high-output head provides four 20 Amp 120V receptacles, plus a 30 Amp 120V locking plug receptacle and a 50 Amp 120/240V straight blade receptacle. It is well-suited for larger workshops, construction sites, or emergency power scenarios where multiple circuits must be fed simultaneously. A consideration is that the higher output requires a robust engine and matching drive components; plan for appropriate engine power and cooling.
Cylinder Head Assembly for Predator/Generac Inverters

This cylinder head is designed for inverter generators with 212cc engines and is compatible with various Predator and Generac models. It’s best for DIY repairs or replacements when rebuilding an inverter-style generator. Best for users who are comfortable verifying model compatibility and performing engine parts replacements. A limitation is that it is a component rather than a complete head unit, so it requires proper installation and integration with existing systems.
ZXDZTZ 7,000W PMG — 220V Brushless

Designed for lighting-focused off-grid systems, this brushless permanent magnet generator drives LED and other energy-efficient loads. It features a copper coil and a voltage regulator for stable power output. Best for dedicated lighting setups in rural or event spaces where high-quality, consistent illumination is required. Not intended for heavy household appliances, so select this head when lighting is the primary load. A limitation is its emphasis on lighting rather than general-power applications.
OLONETO 7KW Belt-Driven PMG — 220V

Pure copper coil construction supports stable power for lighting and small utilities. It’s specifically marketed for lighting use with a 7 kW rating, designed for 220V operation. Best for off-grid lighting-heavy deployments where efficiency and long-term durability matter. A caveat is that it is not intended for heavy household appliances; consider your load profile before selection.
Buying Guide
What should you consider when choosing a belt-driven generator head?
- Power needs: Match surge and continuous watts to your anticipated loads. For workshop or job-site use, a higher surge rating helps handle startup spikes.
- Voltage and receptacle options: Ensure the head provides the right mix of 120V/240V outlets and locking plugs for your tools and devices.
- Engine compatibility: Belt-driven heads require a compatible engine or PTO source. Verify shaft size, RPM, and mounting compatibility with your equipment.
- Portability vs. stationary use: Compact units suit mobile work, while larger heads fit fixed installations or permanent setups.
- Load type: Lighting-focused PMGs excel in illumination tasks but are not suited for appliances or inductive loads.
- Durability and maintenance: Copper windings and sturdy housings support longevity in demanding environments.
Practical questions to guide your choice
- Do you need 120V and 240V outputs, or is 120V-only sufficient?
- Will the head operate alongside other equipment or require independent, dedicated circuits?
- Is lighting a primary or secondary use, affecting PMG suitability?
- Can you provide a suitable engine or PTO to drive the belt system?
- Are you planning portable field work or a fixed workshop installation?
Installation and safety tips
- Follow manufacturer torque and alignment specifications when mounting belts and pulleys.
- Use appropriate guards and shields to prevent belt contact and protect users.
- Ventilation is essential for engine-driven systems to prevent overheating and fuel fumes.
FAQ
- What is a belt-driven generator head?
A belt-driven generator head converts mechanical power from an engine or PTO into electrical power, with a belt drive linking the engine to the generator head.
- What loads are best for belt-driven PMGs?
Permanent magnet PMGs are best for lighting-focused and low-inductive loads. They provide clean, stable output suitable for LED lighting and similar applications.
- How do I choose between 120V and 240V outlets?
Choose based on your tool and appliance requirements. Mixes of 120V and 240V outlets enable running different devices simultaneously.
- Are belt-driven heads easy to install?
Installation depends on having a compatible engine or PTO and proper mounting. Some heads are designed for straightforward connections; others require more setup.
- What maintenance is needed for generator heads?
Regular inspection of belts, pulleys, and electrical connections; ensure cooling and ventilation for the driving engine; replace worn belts as needed.
- Can these heads be used with any engine?
Most heads require a matching belt-drive engine with correct shaft size and RPM. Check model-specific compatibility to avoid misfit or damage.
