What's up everyone! I am really new the solar world and learning fast. In many ways I put the cart before the carriage as they say because I already started ordering stuff. The very first rule I have read is figure out how much power you need first. This cannot be done for me as this is just the start of what's to come. Like a few others I have read about, I too mine crypto. Been in the game a long time and looking for long term solutions to offset my electricity. My bill runs anywhere from $5k - 12k @ .1kwh a month depending on what type and how many machines I turn on. I have a lot of machines that are actually not running (about 75%) due to cost is greater than gain. I want to be able to take advantage of these till they are totally useless. With that said. I wanted to start simple and keep adding as I go. My Electric company said it would take around 750k watts of solar to offset it all, and that ain't gonna happen anytime soon. Also I own 8 houses in my area so I can use net metering to feed all of them if I'm not using it on machines. All in all, I have use for a large system in the long term and going to take advantage of it. I have 70 acres free at my location, so the only limit is my funds. Which are no where near what they were when BTC was up.
I have a 400amp single phase transformer which should be enough till I get really big. It will cost me ~$20k for construction to go to 3 phase.
I am building my Rack Mounts myself with my wife help. She's an architect and her structural engineers will check it for free. Also the price of wood has finally come back down to where you don't need to give blood at least.
With that said, I come to you experts for advice and questions to something I may be doing wrong or if there is a better way. Here is what I have ordered so far.
1. Pallet (27) of Hyundai HiS-S365KI 365 48v Panels - https://www.ebay.com/itm/144926139125
2. Midnite Solar MNPV3 Photovoltaic 3 String Combiner, 600V, 20A - https://www.ebay.com/itm/334728924622
3. 3 20amp breakers for Midnite String Combiner - https://www.amazon.com/gp/product/B004EQK8SA/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1
4. 48V 10KW Solar Hybrid Inverter 120/240V Split Phase 200A MPPT Charge Controller - https://www.ebay.com/itm/285106364164
My questions start here.
1. Is this equipment good/usable for my first array?
2. Do I need to return anything as you think there is better I could get? Or a better price? Every dime I save is that much closer to the next array.
3. I know this a hybrid inverter and I will not be using the batteries at the start, but will add some to power the building with all the equipment in it. Lights/Fans/Batteries/PC etc. Other than that is this a suitable inverter?
4. I know I will need pv cables to run from the array to the combiner. It appears these are pretty much all the same. I haven't seen/noticed sizes other than length. Correct? If so, I have also been told to buy premade cables instead of making them myself. Your thoughts?
5. If the combiner box is say 150' away from the inverter, will 10awg wire carry the current? Or do I need to move to 8awg. I can't find a lot of info on this.
6. What parts/supplies do you see I have overlooked to get this up and running on the grid?
Thank you all in advance! The inverter is here already, the panels are due tomorrow, and the String combiner early next week. I am starting on the racks this week and will definitely post progression pics.
