A Photo Tour of Vingilótë’s Integrels and Power Systems

A Photo Tour of Vingilótë’s Integrels and Power Systems

NOTE: Just to clarify, Vingilótë has two Integrel alternators installed, the first dual Integrel installation. I had blended the pictures originally, but I updated them to put the pictures of port and starboard installs separated out.

Pictures of the engine room, Integrel controller, Integrel control panel, main power cut off switch, engine starter battery and connectors and buses on the engine starter battery.

The Integrels mounted on the Yanmar 4JH57s:

The main compartment in the saloon behind the couch: 48V battery bank, the buses and shunts, the main Integrel controller, the DC-DC converter array between the 48V and 24V battery banks and between the 48V and engine batteries (well, one of them: the other is through a VSR) and between the 24V and engine batteries (as above). To the side the winches breakers. In various places you can see the meters on the power lines and the pink Ethernet cable between the various Integrel components.

The 24V buffer bank.

The DC and AC electrical panels, to left (aft on the boat) and above the DC panel, various Raymarine parts like the Empir bus and data master Axiom Pro 7, in the AC panel the selector between the 30A and 50A SmartPower connectors for shore power, above it the solar panel breakers, and Victron Octo controller. You can see the split bus of the two 120Vac and the combined 240Vac buses and breakers. To the right the Skylla shorepower charger that allows us to limit the draw of shorepower.

The top shelf of the cabinet below the electrical panels with the main Victron components: one of the two inverters, voltage changer, shore power charger, the second of the two inverters.

On the bottom shelf the seven solar charge controllers.

The Integrel control panel in the engine panel in the cockpit. Though each Integrel combines with one we only installed one as it connects to the Integrel controller and all Integrel alternators, and all batteries.

    Very interesting. I assume the main battery bank is 48v but you run power hungry stuff like winches etc from the 24v bank to reduce the needed size of inverters or? I saw that Maxwell now offers a windlass on 48v and if more winches comes in 48v would that mean you could skip the 24v bank or would you still keep it?

    • Edwin Voskamp says:

      That is correct: peak draw vs. sustained draw gets ugly on things like winches and anchor winches especially. To size DC-DC converters for that would not be a good approach.

      If you have 48V winches, fridges/freezers, you can run those directly off of the 48V bank and reduce the size of the 24V buffer bank. Once you get rid of all the 24V draws that have a peak load (realistically most things with an electric motor) you could likely do without it entirely: we have a few 12V loads (VHF, Empir bus) and they’re not spiky draws so we don’t have a 12V buffer battery.

        Maybe by the time my boat is delivered in Dec 2022, there will be more 48v devices. What loads do you still have on ac? I see you have 2 x 5KVA inverters. Are they both 110 vac or is one 230 vac? I remember you have your 230 vac cooktop and oven new.

        • Edwin Voskamp says:

          They’re both 110Vac (well, technically 120Vac) in a split bus design, so they both feed a bus, and combine into a 240Vac bus. That bus feeds to the kitchen for both the magnetic induction cooktop and the steam oven. We’re looking at possibly also using those for water heaters, in-line or boilers.

    Wow – your’s might be the world’s most sophisticated and versatile boat electrical system!

  3. Peter Pawlak says:

    You just show the starboard Integrel generator — did you actually install a dual system and just leave out the pics because they’d all be duplicates? If you just did a single, what was your thinking?

    • Edwin Voskamp says:

      Vingilótë has dual Integrels, the first boat to do so. The photos are from both the port and starboard engine rooms, just not clearly marked as such.

    • Edwin Voskamp says:

      I updated the post and split out photos to clarify which ones are from what engine room.

  4. Jonathan says:

    What kind of of maintenance does the Integrel system need? Are there backup parts to carry? Does it require a 48v system or could it run on 24v? Would you have a link to their maintenance manual?

    Cool setup and thanks for posting!

    • Edwin Voskamp says:

      Nothing really: essentially they’re high power output alternators, so, checking belts, checking wiring. Nothing else should be required.

      It is 48V output (charge voltage obviously is more like mid 50s Volts), so you could step it down to 24V, but in that case you’re not realizing the high output to the battery bank: at 48V, the Integrels produce well over 150 Amps each. If you go to 24V, the amperage doubles, and it is too high to run over wires.

  5. Marc Hawk says:

    Looks like two single installations of the integral system. 6kw each? I believe you could use two on a single motor if you wanted to. At idle how much power do they produce? How about at cruising speed?

    • Edwin Voskamp says:

      Yup. Vingilótë is a sailing catamaran. We have the original 12V alternators on each engine feeding that engine’s start battery (12V), and we replaced the second alternator with the Integrel system.

      Each produces up to 9kW when it gets limited by the Integrel controller so it doesn’t drive more power through the wires than they are rated to handle. We’ve not quite seen 9kW, but there is tweaking yet left to be done.

      I don’t think you can put two Integrels: each one has a controller that manages how much power it takes off, and wouldn’t account for another Integrel on the same engine. Also, they do take power off, so putting two on you would need a fair bit of engine to handle that. We have Yanmar 4JH57 diesel engines, 57 hp each and they handle it easily.

      They produce 2kW each at idle, and at our normal cruising speed, 2,450rpm, they produce 8.5kW each.
