Energy Storage Connector — 1500V DC / 120A Wall-Mount DC Cable Connector
This high-current DC connector is rated for 1500V and 120A, built specifically for the Rich Solar ALPHA 5 PRO energy storage system. Dual-size positive and negative pins physically prevent reverse polarity connection, while a snap-fit, tool-free locking mechanism and IP67 sealing when mated make installation fast and reliable. Sold individually by polarity — positive (orange) or negative (black) — so you can order the exact connector your installation calls for.
⚠ Important Compatibility Notice
This connector is designed and intended exclusively for use with Rich Solar ALPHA 5 PRO batteries. Rich Solar does not recommend or support its use with any non-ALPHA 5 PRO battery or third-party energy storage system. Any damage, malfunction, safety issue, or other problem resulting from improper use or an incompatible battery connection is not covered under warranty, and Rich Solar assumes no liability for such use. Confirm you own an ALPHA 5 PRO system before ordering.
The positive-polarity connector, color-coded orange and sized differently from the negative pin to physically prevent reverse-polarity mating.
The negative-polarity connector, color-coded black with a differently sized contact pin from the positive connector for the same reverse-polarity protection.
1500V DC / 120A — High-Current Rated
Rated for 1500V and 120A continuous current, with a dielectric withstand voltage of 6800V/min and contact resistance of ≤0.5mΩ — built for the demanding current and voltage levels involved in high-capacity energy storage applications.
Dual-Size Pins Prevent Reverse Polarity
The positive and negative connectors use differently sized contact pins, so a reverse-polarity connection isn't physically possible — eliminating a common and potentially serious wiring mistake at the design level rather than relying on labeling alone.
IP67 Sealed, Wide Temperature Range
Fully sealed against dust and water ingress once mated, with a -40°F to +257°F operating range — built for outdoor, high-heat, and extreme-cold installation environments where the connector needs to perform reliably for years.
Product Overview
This energy storage connector is a high-current DC wall-mount connector engineered specifically for the wiring requirements of the Rich Solar ALPHA 5 PRO battery system. At a 1500V DC and 120A rating, it's built for connection points carrying significantly more current than a typical solar panel or charge controller wiring run — reflecting the higher power throughput of a dedicated energy storage installation.
The connector's design includes a meaningful safety feature: the positive and negative contacts use different pin sizes, so the two halves of opposite polarity physically cannot be mated together incorrectly. This removes a common source of installation error rather than relying solely on color-coding or labeling to prevent a reverse-polarity connection, which can cause serious damage in a high-current DC circuit.
Each connector terminates to 4AWG (25mm²) cable via a crimp terminal, with a recommended strip length of 13-14mm. The snap-fit locking mechanism allows tool-free installation and is rated for 100 mating cycles, while an insertion force of ≤60N and withdrawal force of greater than 10N keep the connection secure under normal handling but still serviceable when needed. Once mated, the connector achieves an IP67 rating, and the flame-retardant UL94 V-0 housing adds a layer of fire safety appropriate for a high-current DC connection point.
Purpose-Built for ALPHA 5 PRO Wiring
- Matched to ALPHA 5 PRO Specifications: The connector's 1500V/120A rating, pin geometry, and mounting design are engineered specifically around the ALPHA 5 PRO's connection requirements, not a generic high-current DC standard.
- Not Validated for Other Battery Systems: Rich Solar explicitly does not recommend or support use with non-ALPHA 5 PRO batteries or third-party storage systems — using it elsewhere falls outside the manufacturer's intended use and warranty coverage.
- Replacement & Expansion Use: Useful for replacing a damaged factory connector on an existing ALPHA 5 PRO installation, or for adding additional wiring runs when expanding a multi-unit ALPHA 5 PRO energy storage setup.
- Order the Correct Polarity: Available as a separate positive (orange) or negative (black) plug — confirm which polarity connector your specific wiring run requires before ordering.
Engineered Safety at High Current and Voltage
- Dual-Size Contact Pins: Positive and negative connectors use physically different pin sizes, making an incorrect reverse-polarity mating impossible by design rather than relying on the installer to check color-coding correctly every time.
- Low Contact Resistance: A rated ≤0.5mΩ contact resistance minimizes voltage drop and heat generation across the connection point, even at the connector's full 120A rating.
- High Insulation Resistance: Rated at ≥5000MΩ when dry, providing a strong barrier against current leakage across the connector's insulation.
- 6800V/Min Dielectric Withstand: Insulation tested well beyond the connector's 1500V DC rated voltage, providing significant safety margin against insulation breakdown under normal operating conditions.
- UL94 V-0 Flame-Retardant Housing: Self-extinguishing housing material rated to the highest UL94 flammability classification, an important consideration at this current and voltage level.
Snap-Fit Installation, Built for Wall-Mount Use
- Snap-Fit, Tool-Free Locking: The connector halves lock together with a positive snap engagement — no crimping tool or specialized hardware required to complete the connection itself once the cable is terminated.
- 4AWG (25mm²) Crimp Terminal: Designed for 4AWG cable with a recommended 13-14mm strip length — confirm your cable gauge matches before ordering, and use an appropriately rated crimping tool for the termination.
- Wall-Mount Design: Built for fixed, wall-mounted installation rather than a flexible panel-to-panel connector — appropriate for a stationary battery system's permanent wiring.
- 100 Mating Cycles Rated: Engineered for occasional disconnection and reconnection over the system's service life, such as during maintenance or system reconfiguration — not intended for frequent daily unplugging.
- Compact Footprint: At 2.60 × 0.63 in and 1.31 oz, the connector adds minimal bulk to a wall-mounted battery installation's wiring compartment.
