Look at surrette rolls battery bank with nano fluid can extend battery life to 8000 plus cycles at 80 percent
<h3> 2 YS 62P or 2 YS 30P are good longer batteries in a 48v set up. For longer lasting inverters.</h3>
Look for sma inverter bank they are plug and play up to 4 inverters multi feed ( wind, solar, generator) just hook up and it runs no programming. You just have to set one as master.
We have surrette rolls running that are 12 years old 2 percent loss.
We have cheaper turkish made solar panels as back ip but our main array is 10kw of day4 panels now out of business we have had zero loss over 12 years. Yeah that’s right zero loss they where built crazy tough with zero tolerance. Solar farm in Germany 17 years old one 5.5mw has lost 2 percent so far. Chinese made lose 2-5 percent a year and 10 percent starting stated watts. So a 250 could start as low as 225watt and lose 1.5 watts per year output. Day 4 250watt is 250 min start wattage each pannel balanced to stop micro cascade issues.
Inverters and collection hubs for pannel arrays fail you need spares.
We are testing new nano sealant that supposed helps solar gain… we currently expirience a 10 percent gain in energy output from same arrays just treated with something like rainx.
