Buyer’s Guide: What to Consider

Choosing the right load management device depends on your service size, charging speed, and installation location. Here are key factors to consider before making a purchase.

• Service Size Compatibility: Check your home's electrical service size (60A, 100A, 125A, 200A) to choose a device rated for it. BLACKBOX offers models for 60-100A and 125-200A.
• Charging Speed Needs: Consider how fast you need to charge. Devices support various amperages (16A to 60A). Higher amperage means faster charging but requires adequate service capacity.
• Indoor vs. Outdoor Installation: If mounting outside, choose a weatherproof model like the NEMA 3R versions. Indoor models are fine for garages but not for exposed locations.
• Smart Features: Look for features like solar integration, OCPP compatibility, and dynamic load balancing. ELECQ offers solar modes, while BLACKBOX focuses on simple load management.
• Installation Requirements: All load management devices require a qualified electrician for installation. Factor in installation cost and ensure the device works with your existing charger or plug.

Conclusion

Load management devices are a smart investment for EV owners who want to avoid expensive panel upgrades. The BLACKBOX series offers reliable solutions for various service sizes, both indoor and outdoor, while the ELECQ charger adds smart features like solar integration.

For most homes, the BLACKBOX EVEMS240-100 or 200 models will meet your needs. If you have solar panels, consider the ELECQ. And don’t forget the EV Hover cable holder to keep your setup organized.
