Unboxing and First Impressions
The EG4 100Ah wall mount battery arrived well-packaged. It's surprisingly compact for a 100Ah battery, making it ideal for space-constrained installations. The included mounting hardware (wedge anchors and comm cable) is a nice touch, adding to the convenience. The battery also features small feet, allowing for flexible floor or wall mounting.
The unit's robust build quality is immediately apparent. The casing feels durable and well-constructed, suggesting longevity and resilience. The inclusion of handles on each side makes moving the battery much easier than comparable rack-mount batteries despite similar weight. Initial inspection reveals clean and professional wiring.
Technical Specifications and Features
The EG4 100Ah wall mount battery boasts a 100-amp discharge and charge rate, matching the performance of the rack-mount version. This high amperage capability allows for significant power output, making it suitable for demanding applications. The included 4-gauge, 200°C battery cables are more than adequate to handle the battery's current output and are a considerable cost savings compared to other battery systems that require separate cable purchases.
The battery incorporates Amphenol quick-disconnect connectors, simplifying installation and maintenance. Dip switches provide configuration options, including CAN and RS45 communication protocols for seamless integration with other EG4 equipment. The BMS switch and 125A circuit breaker provide crucial safety features, protecting the battery from overcurrent and other potential issues.
Internal Components and Build Quality
Disassembling the EG4 100Ah battery reveals a design similar to a horizontally oriented rack-mount battery, utilizing high-quality ETC cells. The internal layout is meticulously organized, with cells securely held in place by robust cell holders. Fire arresters are strategically positioned on the lid, further enhancing safety.
The use of consistent 4-gauge wiring throughout, both internally and externally, reflects a commitment to high performance and reliability. Protective cages around the BMS and additional plastic supports demonstrate a superior level of engineering and build quality compared to other comparable brands. This attention to detail minimizes risks and ensures optimal operation.
Testing and Compatibility
Capacity testing confirmed the battery delivers its advertised 100Ah capacity. The precise cutoff at 100Ah suggests a well-calibrated BMS that prioritizes cell protection by preventing over-discharge. The battery communicates seamlessly with EG4 inverters including the 3000W and 6000XP models, via both CAN and RS485 protocols simultaneously, providing versatile integration options.
The battery’s compatibility extends to other EG4 batteries, allowing for easy paralleling to increase capacity. This feature simplifies the creation of larger battery systems without compromising communication or safety. The inclusion of the necessary cables in the package further enhances the user experience.
Conclusion
The EG4 100Ah wall mount battery is a high-quality, feature-rich product that offers excellent performance and versatility. Its compact design, robust construction, and advanced safety features make it a compelling option for various applications. The ease of installation, seamless communication protocols, and included accessories enhance user experience considerably.
Compared to other similar batteries in the market, the EG4 100Ah stands out for its superior build quality, extensive safety features (like dedicated pre-charge resistors and BMS protection), and broad compatibility. Whether you're building a small off-grid system or expanding an existing setup, this battery is a strong contender. Its value proposition is further enhanced by the included cables, saving on added expenses.
