SolarEdge SE100K-US

Is the nominal voltage field programmable on the SolarEdge SE100K-US? We are looking for a similar set of inverters, with a target voltage of ~ 440Y/254 V.

This inverter will be completely off grid (no connection to grid in sight), with critical loads downstream using an ATS to generator before UPS. I am open minded about any suggestions. I have a lot of electrical engineering experience, but have never purchased or programmed an inverter like this before.

Thanks in advance!

What is your purpose for choosing this inverter? This is a gridtie inverter, not an off-grid unit so it is unlikely the type you need for your installation?

You are absolutely right. Although exporting to the grid in the future would be a nice option to have, it is not the initial engineering plan.

I am currently considering two SOL-ARK 60K-3P-480V inverters (https://www.sol-ark.com/sol-ark-60k-3p-480v-n/) in parallel, based on recommendations. I have a request out to Sol-ark regarding the off-grid grid level configurations that are available.

Update:

I have been told that these are the three available off-grid configurations:

Perhaps there is an aftermarket way to hack it if I can gain access to the configuration files or flash with custom firmware?

Does anyone have any suggestions for a different set of inverters that can reach our voltage target? I figure finding the right inverter will be more simple, cost effective and efficient than using buck boost transformers.
