What about this one: Support WIFI GPRS ETHENET 1000w Hybrid inverter with MPPT solar controller 50a 12v 120v https://m.alibaba.com/product/1600215073950/Support-WIFI-GPRS-ETHENET-1000w-Hybrid.html?__sceneInfo={"type":"appDetailShare","data":{"filterKey":"7.8.2_share","cacheTime":"1800000"}}...

How about this unit? https://a.aliexpress.com/_mPvcnjS Nope, it's about the same as what you have already.

Or you could investigate a 240v inverter, running through a center tapped transformer to get the 120v H1/H2 + N. Look for a 240v - 120v stepdown transformer.

Maybe solar cable is rated differently. According to https://www.zw-cable.com/products/Solar_Cable_6mm.html 6mm2 (10AWG) solar cable is rated to 70A, while 4mm2 (12AWG) is rated to 55A. Are you using proper solar cable? 12AWG cable should be fine.

Your Y&H 600w Micro-Inverter is meant for 12v class panels. They give an example of 4x 150w panels. For battery supply, you CANNOT use 12v, it requires 24v, as stated in the specs given in the Amazon listing. So, only 25A. This may be what you need? As for the DC posts, if you use a 4mm banana...

So Bvillebob and Roswell Bob have made it clear that the MPPT conversion losses are less of a concern than losses in transmission from PV panels to charge controller... and that of course also takes into account the transmission cable gauge. Thanks lads. I'll look into optimising those lines...

So, something like this, only for 12v? https://a.aliexpress.com/_mMph7C8 I think your 12v stipulation is your downfall. Inverting 12v to mains requires a large aH rating for your 12v storage system. It may be better (more efficient and cheaper) to hook up your storage as 24v, and have a 24v...

So, I measured the Voc and Isc of my 6 panels today. They pretty much matched Voc rating before they heated up, and exceeded the Isc after they warmed up (although voltage had dropped). Voc was around 21.2v before they heated up, and around 20.2v after the Isc tests. The Isc slowly built up to...

This sheet seems to applicable for the inverter: https://www.solar-thailand.com/pdf/DataSheet-PSW7.pdf

Any opinions on buying the original inverter for $250AUD (circa $180USD) It's a 12v DC, 240v AC 3000w inverter. It's been sitting in his shed unused since he bought the panels (used at the time, I assume). And what sized 12v battery would I need? Assuming 80% efficiency in the inverter (is...

I'm confident I can skip this step. ?

This... is learning right here. I've never heard of PWM being useful only in parallel, but I guess it makes sense. Thank you! I guess if you're crazy and have some "6v" panels (I'm talking those garden light or maybe IP camera or powered gate type panels), maybe series connection would make...

I got 6 panels (advertised as 130w panels) for a grand total of $60AUD. So I paid $10 each. That gives a theoretical maximum of 780w. 2 of them are actually labelled as 140w. I guess it will be simpler to treat them as 130w panels though, unless I want to keep them as a separate system to the...

Here is the page for the panels I suspect these are. https://www.whitworths.com.au/sunyo-polycrystalline-solar-panel Still... very open to suggestions of other possible matches. I know they're not in the best condition, and what brand they truly are is probably inconsequential in the long...

"Solar Module" isn't very helpful. I've tried to hunt around and these seem to match the specs for some panels being sold from a "boat" shop. Also, the inverter which was available as a separate purchase I have seen mentioned in a For Sale listing of a river boat house. So I'm assuming these...

Ok, I'll throw up some photos as no one has said no.

Maybe you could look at something like this: MUST PV18 VPM Series 1000W 1KW 12V Home High Frequency MPPT Solar Inverter https://a.aliexpress.com/_mOPBBVW

Yup. That's the only thing I found also. Maybe it's just an inverter, but can use AC to charge the battery also. For solar, a separate charge controller would be necessary.

G'day all. I've decided to (very slowly) dip my toes into the solar power arena, and purchased some (pretty old) used panels for $60, and I was wondering if this is the right place to ask for help with identifying them?

Are you looking for brand new? I recently picked up some used panels (800w total) and while I was there I was offered the chance to purchase a Uranus NP 3012E - 12v 3000w solar charger inverter. I don't know very much about it, but the dude says it can do AC charging of the 12v battery storage...
