Egis Mobile Electric Marine Electrical Systems — Advanced Battery Management & Power Distribution for Your Boat

Managing onboard power reliably is one of the most critical parts of any boat build or refit. Egis Mobile Electric has built a strong reputation among professional marine installers for components that genuinely hold up through salt air, vibration, moisture, and temperature extremes. Founded in 2017, they manufacture marine electrical components including ACRs, circuit breakers, disconnect switches, fuse blocks, and power distribution solutions engineered for demanding marine environments — and received the IBEX Innovation Award in 2022 for their XD Series Relays.

Their XD Series in particular takes a smarter approach to power management. The relays deliver a 35–75% reduction in mounting space and weight through an advanced bi-stable solenoid design, eliminating dead start batteries by sharing charging across banks and isolating them when no charge is present. Off-state current draw is just 1.3 mA — the lowest in the industry — and every XD Series product carries a 4-year warranty through the manufacturer.

Products & Applications

• Automatic Charging Relays (ACRs) — Automatically combine and isolate battery banks; 12V/24V, 160A rated; ideal for dual and triple battery sailboats and powerboats
• XD Series Flex Relays — Programmable as ACR, remote switch, or LVD; single, dual, and triple configurations; expandable via link busbars and compatible with NMEA 2000 REBELLION MARINE
• Fuse Blocks & Circuit Protection — IP67-rated MIDI fuse blocks with stainless steel studs and latching covers; RT and CT Series in 6–18 position layouts; for engine compartments, nav stations, and electronics circuits Defender Marine
• Busbars & Ground Blocks — Sealed to IP66/IP6K9K with stainless steel cable lug studs; MT Series integrates ground busbars with fuse outputs for clean panel builds Egismobile
• Battery Disconnect Switches — 500A mechanical contactors for main battery isolation; meets ABYC safety recommendations; pairs with XD relays for manual override
• Time Delay & Low Voltage Disconnect Relays — Protects electronics during engine start and sheds loads when battery voltage drops; ideal for anchor watch and storage

FAQ Section

Are Egis products compatible with lithium batteries?

Yes. The Flex L XD Series variants are specifically engineered for LiFePO4 systems, handling lithium charge profiles and voltage thresholds that standard AGM-focused relays can't manage properly.

Why does bi-stable solenoid design matter on a boat?

It holds its relay position without drawing continuous power. At just 1.3 mA at rest, the XD Series won't quietly drain your battery bank while you're on a mooring or at anchor.

Can I expand my Egis system as my electrical needs grow?

Yes — the XD relays, fuse blocks, and busbars are designed to interconnect via link busbars, so you can start small and scale to a full multi-battery system without replacing existing components.

Do these products need a professional installer?

Not always, but Egis designs with installers in mind — keyed connectors, LED status indicators, and detailed documentation simplify the job. For high-current or multi-bank systems, a certified marine electrician is always a smart choice.
