Best 3 Phase Solar Inverter | The Off-Grid Shop

[@ZigZagRailway]

We are looking to setup a system that keeps a critical retail setup running. For us that will be Freezers, Fridges, some lighting, point of sale, Phones & Comms. We have recently had three phases run to the board, but currently only pulling from one phase

I would recomened installing some consumption monitoring. You will then have some great data to make a better decision on what you require in a black out situation. Or do you guys have smart meter?

A way to get extra value out excess energy on top of mining crypto would be to water cool your rig and heat water with it. The power that goes into rig essentially comes out entirely as thermal energy, and a little kinetic/sound (fans)

We have benefited from the excess heat heating the floors of the house. It's been great. Having old timber floors the cold air used to come up through the floors. Now it's nice and warm. It has increased the inside temps by 3-5 degrees.

@@mikehaydon89 nice yes, perfect use

[@TheOffGridShop]

We have looked at that. The floods put mining on hold for us.

Thanks very much Mike, cannot you charge the battery during the night when it is cheaper and then use that power during the day when energy is more expensive? I currently already have a PV system with 3 phase inverter. Want to add battery storage, not for backup but mostly for shifting energy cost. Very cheap at night and expensive during the day. Would this be possible with a system like this? IS it possible to program when charging is possible from the grid, so it only charges in certain hours(during night when cheap) and from the PV system.

Thank you. In Australia I use the wholesale network prices. And of a day I pay 1-10 cents. Of a night it's 16-22 cents. With all the solar in the network now. Day time is the cheapest.

[@aurelianmunteanu7680]

so for 3 phase with Victron you need 3 multiplus units, 1 for each phase.

[@TheOffGridShop]

Yes of you want to back up 3 phase loads. I have 3 phase PV inverters and I only back up one phase on batteries.

Hello, I'm starting a tiny house / rv / shipping container house business. Will be starting with 10 spots. Putting in a coin/card laundry into a shipping container for the folks who live there. Electrical Requirements of a model of commercial washers we are looking at: 15 / 400 / 50 / 3 / 4 wire + ground, this is another model 24 / 400 / 50 / 3 / 4 wire + ground. Thats kW/Volts/Freq/phase/wire. We are located in the United states. I'm familiar with solar systems, but never designed a three phase system. Use Magnum and Growatt inverters for single and split phase application. Would like your input for this wash room. We will be using server rack LiFePo4 batteries, and a roof mounted array, and ground mounted array, with whatever controllers/inverters are best for this application, grid tied, solar first then battery then grid, with generator backup for the customers. Thanks for input!

[@TheOffGridShop]

Sounds like a very exciting project. If you would like us to help you with a design we do offer This as a service.

[@TheOffGridShop]

As for the wash room. I would recommend doing an AC coupled system. And have in operation during sun hours like 9am to 4pm in summer and 10-2pm in winter. It will save you a ton in battery storage and headaches. The other option is to be sustainable. You could run a back up generator on vegetable oil? You can get that normally easily and can make your own biodiesel.

@@TheOffGridShop What do you charge for consultation?

@@TheOffGridShop Great idea. I wanted to have a small cafe/kitchen out of a 20' container, if we were to run a veg oil fryer we could recycle the oil into a backup gennie. Heat waste from the generator could be dumped into a central boiler, same with excess energy from bitcoin miners,. Metering access to those services are also a good idea which I'll implement.
