Power Install System

Power Install System 250 – compact main power distribution for boats, yachts & vehicles

The Power Install System 250 is a modular system from philippi for main power distribution up to 250 A continuous current in 12 V and 24 V systems. Main switches, fuse bars and busbars are screwed directly together via solid copper connecting bars instead of being wired individually – more compact, faster to install and with fewer contact resistances.

In brief: Instead of connecting main switch, fuses and distributor with flexible cables, the precisely fitting components are plugged and screwed directly together. How the system is structured and which variants are possible is shown on the Power Install System page.

The advantages at a glance

• No complex individual wiring between the main components
• Fewer cable lugs and therefore fewer contact resistances
• Space-saving, clear design
• Modular expansion at any time
• Well suited to lithium systems with high charge and discharge currents

The components

Typical configurations

• Main power distribution for starter and service battery
• Manual or remote main switch directly at the battery
• Emergency parallel connection to start the engine from the service battery
• Charging or isolating relay for automatic battery separation
• Protection of high-current loads such as inverter, anchor windlass and bow thruster

Frequently asked questions about the Power Install System 250

Which voltages and currents is the system designed for?

The Power Install System 250 is designed for 12 V and 24 V systems and for continuous currents up to 250 A. It thus covers the main power distribution of typical yachts, motor boats, motorhomes and expedition vehicles, including lithium batteries and inverters. The fuse for each outgoing cable is chosen according to its cross-section.

Can the system be expanded later?

Yes. The system is modular: further fuse bars, busbars, switches or relays are simply added via the connecting bars without rebuilding the existing installation. The main distribution can thus grow when an inverter, a second battery bank or further high-current loads are added later.

How are the components connected?

Main switches, fuse bars and busbars are screwed directly together via precisely fitting connecting bars and bridges such as EBV, SDV and SDV-N. Flexible individual cables between the main components are largely eliminated. This saves space and installation time and reduces the number of cable lugs where contact resistance can arise.

Can I integrate a remote main switch?

Yes. In addition to the manual EBH 250 battery main switch, remote main switches can be integrated, for example the XD series with 500 A. The battery can then be disconnected from the helm or via bus, while the switch itself sits directly at the battery, where the unfused cable section is shortest.

How does the emergency parallel connection for engine starting work?

The system can be set up so that the service and starter battery are connected together when needed. If the starter battery is flat, the engine can then be started from the service battery. Alternatively, a charging or isolating relay automatically connects the batteries when charging and separates them at rest.
