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...

I have been very impressed with super capacitors in my electrical engineering experience. I would like to explore the cost effectiveness of building a super capacitor bank for energy storage to use at night time, especially considering the costs of these components from overseas is decreasing as...

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!

I am looking to engineer a system that maintains and stores 1,000 L of a glycol/water mixture at -50 C during the day. My calculations are that it is more economic to store a large volume of cold liquid rather than buying the batteries to compress on demand in the night time. I also have an...

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...
