Tapa Inverter Module Assembly for Harbor Freight Predator 9500 Watt Inverter Generator
This inverter module is designed for some Harbor Freight Predator 9500 watt models, specifically generators like model 57080 and 59188. Best for owners who have verified their current module matches the pictured version and have confirmed the problem is due to the inverter board. Not all Predator 9500 units use this exact module, so careful comparison with the photos is essential. If the current module is confirmed damaged, this can restore function. A caution: customers who try this module without confirming compatibility may incur losses from returns and packaging issues.
Who should consider this: buyers with a Predator 9500 setup seeking a direct replacement and who can verify their module visually matches the product images. Choose this if your current inverter board is the same and you need a like-for-like replacement. Avoid this if your Predator 9500 has a different board design or an alternative model number not shown in the pictures.
Tapa Inverter Module Unit Compatible with Harbor Freight Predator 3500 Watt Inverter
This module fits some Predator 3500 watt inverters, notably models 56720 and 63584, with an updated version featuring three capacitors and two connectors. Best for buyers who can confirm their unit uses the two-connector design and match the pictured modules. The listing warns there are different Predator 3500 modules from different manufacturers, so exact connector counts and photos must align. If your model matches the two-connector version, this is a solid replacement. Limitation: there is another 3500 module with six connectors not compatible with this one.
Who should buy: generator owners needing a newer-style module to replace an older two-connector version. Choose this if your connectors match, and you want the updated capacitor arrangement. Avoid this if your unit uses a different connector count or another manufacturer’s module.
Tapa Inverter Module Assembly for Harbor Freight Predator 2000/1600 Watt Inverter Generator
This is the newer version for Predator 2000/1600 models, featuring a single capacitor. The seller notes the old two-capacitor version is no longer produced. Best for buyers updating from an older two-capacitor design who want the latest module with one capacitor. The packaging and connector alignment in photos 3 and 4 should be matched—if your unit’s plugs differ, avoid ordering. The listing mentions two OEM manufacturers for Predator 2000 modules, which means non-compatible options exist; verify connector count and image details first.
Who should choose this: Predator 2000/1600 owners seeking the current-generation module with a single capacitor and clear connector guidance. Choose this if your unit uses the two-plug configuration shown. Avoid if your Predator has a different connector layout or an alternative module from another manufacturer.
Tapa Inverter Module Compatible with Champion 2500W Dual Fuel Inverter
This module is listed as compatible with Champion 2500W dual-fuel inverters. Best for Champion owners seeking a direct replacement module that matches the 2500W dual-fuel configuration. The product description points to compatibility with select models, so buyers should compare connectors and photos to their unit before purchasing. Limitation: compatibility is not universal across all Champion 2500W units; confirm the image and connector layout align with your current module.
Tapa Inverter Module Compatible with Predator 8750/7000
This module is designed for Predator 8750/7000 watt inverters and notes two different boards exist for these models. It highlights a configuration with four copper coils, six capacitors, and three connectors, with emphasis on matching photos 2–5 to ensure compatibility. Best for high-watt Predator owners who can verify connector count and coil/capacitor configuration. A caution: there is another 8750 module variant (two coils, four capacitors) that is not compatible. Make sure you select the exact version for your generator.
Buying Guide
- Check exact model compatibility: inverter modules vary by model, watt rating, and even by OEM manufacturer. Visual matching of connectors and coils is essential.
- Connector count matters: some modules use two connectors, others three or six. Match the number and layout to your generator’s wiring harness.
- Capacitor configuration: updated modules may swap capacitor counts (for example, one vs. three or four). This affects electrical characteristics and fit.
- Model-specific notes: Harbor Freight Predator models and Champion units often have parallel versions; confirm model numbers, not just wattage.
- Return considerations: if a product is listed with strict compatibility notes, verify thoroughly before ordering to avoid packing damage and return losses.
