If you want to eliminate any possibility, you could set up a couple panels with DC charge controller near the satellite modem and use an ethernet-fiber media converter on both sides. The fiber will be non-conductive. A reasonable enough path is to use Ethernet surge suppression on both sides...

If you want a transformer, you could use 208:240 V split phase or a Scott-T transformer to better balance the load. Many three phase generators are reconfigurable to split phase, if there are enough poles/winding taps to do so on yours.

You could need an isolation transformer (two in open wye/delta or three) to avoid troubles. A more custom transformer could also act as current shunt (similar to neon sign transformers with limited current). However, it may be more cost effective to accomplish this with buck boost circuity...

2.5 kV !?

Hopefully, it is possible to reconfigure in the software. However, if it is not, you could consider a little DIN rail/MCB box with a three minute delay timer (upon power on) and a contactor.

There are better ways to do this without messing with the utility. Put a relay, contactor or ATS of sorts between the appliances you want to power (e.g. office circuit, hot water tank, washing machine, microwave circuits) and the micro inverter. That way, you are doing it more safely and without...

How many meters are you allowed to have - one per structure or address? So you could subdivide your own property to get more meters, in theory?

A side note; something cool about having the neutral in a three wire 208Y/120 or 220Y/127 V service is that you can derive a system with the missing phase to properly drive three phase equipment if you ever need to. I.e. by using an open-wye open-delta transformer setup: or

I was looking at the manual of the CSI-100K-T400, but I am not clear whether it has off-grid functionality and the precisely adjustable voltage. If you have any experience with this line of units, please let me know...

Hello, Would you guys please send your Growatt firmware ".bin" files to me if you happen to have any available? I am a software developer thinking of purchasing some Growatt inverter, but I want to check whether it is possible to change my custom EPS voltage requirements. Thank you

Hello, I am looking for an inverter or series of inverters that can be combined to output 440Y/254 V 50 Hz at 100 kW (~33 kW per phase). I am having a hard time finding this. I was in discussion with Gro-watt about custom firmware, but the communication went dead. Is there a way to override...

Perhaps export to the grid, or boil the the ocean.

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...

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...

OK, I think that arithmetic nips it in the bud. Thanks for that. The only use case I can comprehend is perhaps a small bank to handle the brief surge demand of power through an inverter for things like motors or heaters starting up.
