Haikuo FRP battery top covers are molded to shield battery racks and modules across solar, wind, and grid-scale energy storage installations, pairing electrical non-conductivity with corrosion resistance and, where specified, flame-retardant resin formulations.
As outdoor battery energy storage deployments expand into coastal and humid regions, FRP top covers give installers a lightweight, non-conductive enclosure component that avoids the corrosion, rust, and stray-current risks a metal cover can introduce.
What Sets FRP Battery Top Covers Apart
These features give FRP battery top covers an edge over conventional alternatives:
- Non-Conductive Construction: A fully insulating cover removes short-circuit and stray-current risk around battery terminals.
- Flame-Retardant Resin Option: Available in UL94 flame-retardant resin formulations to meet battery safety compliance needs.
- Corrosion Resistance: Resistant to moisture, salt air, or battery off-gassing byproducts over the installation’s service life.
- Lightweight Installation: Considerably lighter than steel or aluminum covers, simplifying field installation and servicing.
- Weatherproof Sealing: The molded profile accommodates gasket sealing for outdoor IP-rated enclosure assemblies.
Key Advantages of Haikuo FRP Battery Top Covers
For energy storage system integrators, Haikuo FRP battery top covers deliver a corrosion-free, non-conductive enclosure component built for long-term outdoor use in solar and grid-storage projects.

| Corrosion & Rust Immunity | 100% Resistant | Poor to Moderate (depends on coating) | Good |
| Flame-Retardant Option | Available (UL94 V-0 resin) | Not applicable (metal does not burn but conducts heat) | Limited (standard plastics) |
| Weight Efficiency Index | Light | Heavy (steel) / Light (aluminum) | Light |
| Structural Strength | Good (glass-reinforced) | Excellent (metal) | Lower (unreinforced plastic) |
Targeted Product FAQ
Q1: Why use a non-conductive cover on battery energy storage racks?
A1: A FRP battery top cover eliminates the short-circuit and stray-current risk that a metal cover can introduce if it contacts exposed battery terminals or busbars.
Q2: Is a flame-retardant version available?
A2: Yes, we offer UL94 V-0 flame-retardant resin formulations for projects with specific battery enclosure fire-safety requirements.
Q3: Can covers be molded to match our specific rack or module dimensions?
A3: Yes, send us your rack or module drawing including cable entry locations and we will confirm feasibility and tooling lead time.
Q4: How does FRP perform against battery off-gassing compared to metal?
A4: FRP resin is chemically inert to typical battery off-gassing byproducts and resists corrosion better than an unprotected metal cover over the installation service life.
Q5: What is the typical lead time for a custom mold?
A5: New mold tooling typically requires 3-4 weeks; once tooling is complete, production lead time is 10-15 days per batch.
