2018 R23 No Factory Inverter - Which Inverter to Install??

[BillW]

Our used 2018 R23 with 200HP Yamaha Outboard did not come with a Factory Installed Inverter - we would like to install one and are debating how large a unit to get. We currently live in Connecticut where AC is probably not needed while on the hook, so we are thinking that a 1500W unit should be big enough for taking turns with the microwave (1000W), coffee maker (600W), and water heater (750W) with the Yamaha occasionally recharging the batteries. Seeking feedback and thoughts from other R23 owners with the Factory Installed Inverter or those who have installed their own inverters.

So, if you have R23 inverter usage or installation experiences, please pass along your guidance and suggestions for an inverter - brand, model, likes, dislikes, problems, successes, etc - all comments would be appreciated! I have done electrical work on land and some limited electrical work on smaller boats, so I know the basics, but any special guidance about installing an inverter specifically on the R23 would be helpful - photos, wiring diagrams, do's, don't's, etc.

Please help, thanks!

I purchased my C26 no generator, no inverter. I wish I purchased it with a generator but at the time it seemed like money not well spent. I also did not want the inverter that Fluid Motion was using 1500W modified sine wave Promariner. I wanted a minimum of 2000W and pure sine wave. I Purchased a Kisea 2000 W SWXFR-1220. This inverter can be hard wired with GFCI protection. Specs are 2000W continuous output (16.6 amps) with peak output 4000W (Momentary) There is a removable control panel that can be mounted at the main breaker panel. I did not use the auto transfer switch. I control the inverter on /off. Installation is easy. The most important part of wiring the inverter is confirming it is isolated from the shore power circuit. Hot and neutral. If your R23 has the rotary selector switch.I have posted a picture of the switch. Isolation can be done using the rotary sector switch. The Location of the inverter should be as close to the house batteries as possible and in a dry well ventilated area for inverter cooling. Follow the installation manual as per cables sizes. When questionable go with the larger size cable.

Photo of breaker panel with rotary switch. Positioned in inverter. 120 v output ready. I have the complete panel wired to the inverter. I can use it to power the outlets, Microwave/convection oven, electric stove top, hot water heater, and Air unit. (I do not use the air unit for cooling just air circulation)

This photo shows the inverter control panel that was removed from the inverter and mounted remotely. It is mounted directly below the breaker panel. All inverter functions can be controlled from this remote with the exception of the GFCI reset.

If you have any questions about wiring the 10/3 boat cable from the inverter to the rotary switch I have a drawing of the schematic that I used.

Bill,

We also have a 2018 R-23. We've got the switch for Shore Power / Inverter and Charger We assumed that an Inverter was installed. Is that how your Tug was configured (before you then added an inverter)?

Cheers!
Brad

We ordered our 2021 R-23 with A/C underway as an option, so it shipped with a Kisae 2000W Pure Sinewave inverter. It is in the cave behind the port side of the electrical panel.

water heater (750W) with the Yamaha occasionally recharging the batteries.

I don't know how long you would be running each item you mentioned but the water heater is a red flag. Do you mean a heater for a cup of coffee? I would use the microwave for that. If you mean for system hot water please be careful. Could I suggest you watch the presentation and use the power consumption spreadsheet to check your anticipated usage. Check out this article https://marinehowto.com/a-look-at-inver ... ve%20loads.

The factory, as an example, does not wire the water heater to the inverter on diesel boats of similar size. The R25SC has a d3 150 engine with a 160A alternator. I always start the engine before using the microwave even if only for a couple of minutes. The Yamaha has a much lower output. Even if the charging power is available there is a limit as to how fast you can recharge your batteries. Before installing the inverter I would install a Victron shunt and use the app on your phone to check electrical usage and battery performance.
