Power Install System 250 – Compact Main Power Distribution for Boats, Yachts & Vehicles
The Power Install System 250 is a modular system for compact main power distribution up to 250 A continuous current in the on-board electrical systems of sailing yachts, motorboats, motorhomes, and special vehicles. Solid galvanized copper connecting busbars directly link main switches, fuse blocks, and distributors – eliminating complex individual wiring, minimizing contact resistance, and providing a space-saving design.
Briefly explained: The Power Install System 250 replaces flexible individual cables in main power distribution with directly bolted components featuring copper busbars – faster to install, more compact, lower contact resistance, fewer sources of error.
What is the Power Install System 250 and what is it used for?
The Power Install System 250 is a modular installation system for main power distribution in 12V and 24V on-board electrical systems up to 250 A. It directly connects main switches, fuse blocks, bolt-down fuses, and power distributors via precisely fitted solid copper connecting busbars – eliminating the intermediate points and contact resistances typical of conventional wiring.
Typical applications: Sailing yachts, motorboats, expedition vehicles, motorhomes, and special vehicles – especially on-board electrical systems with lithium battery systems or high power demands.
Installing Main Power Distribution – How Does the Power Install System Work?
Instead of connecting main switches, fuses, and distributors with individual flexible cables, all components of the Power Install System are directly bolted together via precisely fitted copper connecting busbars. This significantly reduces installation effort, eliminates unnecessary connection points, and minimizes contact resistance. Assembly can be done very time-efficiently.
The main advantages at a glance:
- No complex individual wiring between main components
- Minimized contact resistance due to direct copper connections
- Space-saving, compact design
- Modular expandability possible at any time
- Well suited for lithium systems with high charging and discharging currents
Which configurations are possible with the Power Install System 250?
The system has a modular design and can be flexibly adapted to individual requirements:
- Main power distribution for starter and house batteries
- Integration of manual or remote-controlled main switches (FHR, THR, FHC)
- Emergency parallel connection for engine start via the house battery
- Integration of charging and isolation relays for automatic battery separation
- Protection of high-current consumers via bolt-down fuse blocks
- Protection of continuous-plus and small consumers via auxiliary fuse blocks
- Expansion with additional circuits and consumers
Is the Power Install System 250 suitable for lithium batteries?
Yes. The Power Install System 250 is explicitly designed for modern on-board electrical systems with lithium batteries, inverters, charge boosters, and high-power consumers. The direct connection via solid copper busbars reduces contact resistance and sources of error – both critical factors in lithium systems with high charging and discharging currents, where voltage drops and unstable connections are particularly problematic.

Frequently Asked Questions about the Power Install System 250
What voltages and currents is the system designed for? The Power Install System 250 is designed for 12V and 24V on-board electrical systems and is suitable for continuous currents up to 250 A.
Can the system be expanded later? Yes. The modular system can be expanded at any time by adding further components – fuse blocks, relays, switches – without fundamentally altering the existing installation.
How are the components connected? The connection is made via precisely fitted solid copper connecting busbars that are bolted directly together. Flexible individual cables between the main components are largely eliminated.
Which vehicles and boats is the system suitable for? The Power Install System 250 is suitable for sailing yachts, motorboats, expedition vehicles, motorhomes, and special vehicles – wherever compact, reliable, and expandable main power distribution is required.
Can I integrate a remote-controlled main switch? Yes. The Power Install System 250 supports the integration of remote-controlled main switches of types FHR, THR, and FHC – for electrical main power disconnection without direct manual access to the switch.
How is the emergency parallel connection for engine start realized? Through appropriate configuration in the Power Install System, house and starter batteries can be paralleled when needed – to start the engine via the house battery even if the starter battery is discharged.
