FranklinWH MAC-R1V1-US Meter Adapter Controller

FranklinWH MAC-R1V1-US Meter Adapter Controller (MAC 1) – Simplified Home Battery Installation

The FranklinWH MAC-R1V1-US Meter Adapter Controller, also called the FranklinWH MAC 1, is a compact and intelligent meter socket adapter controller designed to make installing FranklinWH home battery storage systems dramatically easier and more affordable — especially in homes with meter-main combo panels.

By mounting directly between the utility meter and a third-party meter socket adapter (MSA), the MAC eliminates the need for invasive main electrical panel upgrades, extensive rewiring, or adding sub-panels. This innovative solution can reduce typical installation time from several hours to as little as 20 minutes, significantly lowering labor costs and project complexity for solar + storage retrofits.

Key Features & Benefits

• Ultra-Fast & Non-Invasive Installation — Avoids panel modifications and utility red tape common with traditional battery backups.
• Whole-Home Energy Management — Serves as the central gateway for seamless grid interaction, automatic whole-home backup during outages, real-time metering, and intelligent control of solar, battery, and loads.
• Seamless Compatibility — Works perfectly with FranklinWH aPower 2, aPower S, and aHub systems.
• Low Power & Reliable Design — Fanless operation with only 7W consumption, Type 3R enclosure for indoor/outdoor use, and a robust 15-year warranty.
