I haven't stayed current on pricing for 15 years or more. So can not comment on price. The specs look good if it will support your load and you have 48 V battery banks.
Moving up to 48v allows you to move twice as much power thru the same size wiring as a 24v system.
4000 watts at 12 volts requires 333.3 amps.
Yeah my cabling is WAY oversize and I like it that way. IIRC I can run 500 amps continuous through my double or was it quadruple cables the size of my fat index fingers! Copper was cheap enough back when I bought them planning them to fit ANY need that may arise as the years progress! Pretty sure I am running quad cabling! I know over kill but they NEVER get warm!!!!!!!!4000 watts at 12 volts requires 333.3 amps.
You gotta have some damfat, expensive cables to handle that!
A 48v system only requires 1/4 of that, 83.3a, to supply the same 4000w of power.
Same power, much less expensive copper cabling.
Yes they are expensive. After 8 or 9 years I've had zero problems with my Magnum inverter. I don't have enough experience with solar so I don't know how they compare with other brands.
I'm really pleased with my 2 volt × 12, 1169 ah Rolls batteries.
I hear they are super nice and long lived when taken care of. That's one heck of a bank! My total was a little over half that.
@Supervisor42 & @UrbanHunterAt this point I'm like @zoomzoom using a 12V-4000 watt unit with really big cables and very short cable runs...
In a vehicle the high amp draw only lasts a few seconds during cranking.@Supervisor42 & @UrbanHunter
Now you got me thinking if my wire may be inadequate.
I have (3) 100Ah batteries connected in parallel. I'll have to confirm but pretty sure I'm using 2-gauge wire between them. Each cable is about 1 foot.
From the last battery, I'm running 2-gauge wire to the inverter. Distance is a foot or two.
Is that heavy enough? I'm thinking of other 12v systems (e.g. vehicles) that have very high CCA's but don't use wire that are super thick.
If you only have 2 or 3 foot of wire then 2 gage is fine. The size of wire is impacted greatly be the length, much more so than many people realize. Checking for heat at the end of a long hard run will answer your question. Cables generally warm up a little, less than 7 degrees if everything is properly sized. My personal general rule of thumb is that if you can hold your hand on it at max power and draw after an hour of run time then your fine. Most people can hold an item at 120f for a minute or so but they know it's hot at 130f most people tent to let go QUICK! Personally I tend to oversize wire just because it's cheap insurance against problems. Plus things generally work better when they run cool versus hot.@Supervisor42 & @UrbanHunter

I’ve done a lot of reading/watching about wind power. Almost everybody that bought one regrets it because the marketing materials are based on best case scenario, and reality is the opposite. At our next house I plan on installing an anemometer and logging a full year of data before deciding which, if any, wind turbine to spend money on.
