Three phase 100 KW Inverter recommendation

[mapsofilti]

Hello,

I am looking for an off-grid inverter recommendation for 100 kW with a specific voltage of 440Y/254 V. 50 Hz is preferred, though we can also work with 60.
I am using hundreds of 350 W panels, so I can configure the wiring of the panels as is best for the inverter.

Thanks in advance!

100 kW with a specific voltage of 440Y/254 V. 50 Hz is preferred,

100kW - really?
are you powering a small factory/business?
I have seen some commercial grade inverters on the MPP website (maximum solar) but I know nothing about them.

I was looking at the SolarEdge SE100K-US, (480Y/277 V) but I am not sure that its voltage will be adjustable and I would not want to budget extra for buck boost transformers if there is an inverter that can put out exactly what we need.

I am diverging a bit from a typical setup, specifically because of the climate of my country. Instead of investing in a lot of batteries, I am putting more panels and a larger inverter to power a custom cooling system. All day, at least 30 HP (~25 kW) of compressors will be running to cool liquid which will be circulated throughout the house as radiant floor cooling and/or through air heat exchanges in the night. At night time, I am not expecting to use more than 2 kW to power some electronic devices (e.g. TV, gaming PC, chargers, fans) and the pumps and air circulation for this custom cooling system.

In the day time, I expect the loads to be substantial (sorted by estimated frequency of demand or use time):
- 25 kW estimated for the liquid cooling compressors
- 17 kW for 60.000 BTU air conditioner
- 22 kW for EV charger
- 6 kW x2 250 L hot water tanks
- 2 kW x2 for combo washer dryer units that can take several hours to run
- 0.6 kW gaming PC
- 0.5 kW lighting
- 3 kW kettle
- 1.5 kW microwave
- 6 kW cook top
- 6 kW sauna
- 2.4 kW hair dryer
- 2.4 kW oven

Sol-ark 60k? Parallel 2.

There may be better options for efficient cooling units, instead of the huge inverter.
There are members here on the forum knowledgeable about this equipment, not my forte.
In-floor cooling can result in condensation and mould growth - be careful with the design of humidity controls.

Sol-ark 60k? Parallel 2.

I will take a look at Sol-ark, thanks for the suggestion. I found the model here: https://www.sol-ark.com/sol-ark-60k-3p-480v-n/. They even have a specs sheet in Español. I am curious to consider running multiple inverters as separate systems as well, depending on the capacities; i.e. one or two larger inverters for the day-time only loads (air conditioner, water compressors, hot water tanks, EV charger, laundry etc.) and a smaller inverter for the night time or 24/7 circuits.

I am open minded about suggestions! Thanks for the heads up about mould growth. That is one of the main reasons I am considering using more conventional heat exchangers with airflow.

This is what I've found on the Sol-ark voltage selection. Do you guys have any more insight with those particular style of inverters?



Update: I have a request out to the Sol-ark engineering team. I will post when I hear back!
