Recommended equipment

[Just_Askin]

I'd like to thank you all for your help so far. The battery issue has been resolved and I'm going with 2 @ 12v 280ah batteries in parallel.

Now it's time to look at other equipment like a 50-70ish amp charge controller, a 2000 watt inverter, shore power 12v battery charger, and DC - DC battery charger from my truck's battery/alternator.

From what I've read Vectron appears to be popular and reliable, but I haven't found that they make everything I've listed above.

I want to first focus on purchasing the charge controller and inverter and then we can look at some of the smaller items.
Here is a Vectron inverter, but it's only 1200 watts https://a.co/d/hY09cz9 I'm looking at another brand that's bigger and has additional surge amperage https://a.co/d/cgWfBg6

Here is a charge controller I found on Amazon, but I don't know if it's big enough 100v 50a https://a.co/d/2rFCF05
Here is a bigger one at 150v 70a https://a.co/d/9ep90NI is 150v too high?
FYI: I am placing my panels in 2s2p configuration. The voc is 20.4 and isc is 13.9.

Please let me know what you think of these. I am also open to your suggestions related to size and brand. If you have something in mind that you think will meet my needs and can provide a link to the product, I would greatly appreciate it. Thanks again for all your help.

Giandel is generally a reliable brand so that is good.

Look at the Victron Quatro series of inverter chargers. The phoenix stuff is just inverter. For MPPT you can't go wrong with Victron... there are other brands that are cheaper and just as reliable if you want.

I am using one of these for a UPS on a server here at the house... combined with a victron MPPT it is a good little system.

Amazon.com

There are lots of options.

If Voc and Isc You provided are for one panel and You will be using 2s2p configuration on 12 V system, than Victron Smart Solar 150/70 is the way to go: total Voc will be 40.8 V and Isc will be 27.8 A - both far below the MPPT limits.
The value to look at in this case is the max charge current: most likely the total power of the 4 panels will be close to 1000 W, which at ideal conditions will result in 70-80 A of charge to 12 V battery.
In datasheet it corresponds nicely to 150 / 70 MPPT (no problem with 150 V - just a nice safety margin).

I'm so confused.. What in your list doesn't Victron make? You want the Multiplus victron as they're 2000/3000/5000w. OrionXS DC DC converter and whatever MPPT fits. on an MPPT those are the MAX voltages/amperages, there isn't a too high, you're just spending more than you need to. I run a pair of 150/70 MPPTs and only pull 60-70v/40a from it. They're VEcan so have a network cable vs the vedirect plug which I hate. Plus oversizing allows them to run cooler and more futureproof incase I want to reconfigure. I'm unsure if there's any drop in efficiency by oversizing but I doubt it.

I recently purchased a Victron Energy SmartSolar MPPT Tr VE. Can Solar Charge Controller (Bluetooth) - Charge Controllers for Solar Panels - 150V, 70 amp, 12/24/36/48-Volt.

I didn't notice the VE.can as an additional item. That's ok, isn't it? It's just for adding additional units?

 

[JanisD]

That's completely OK - You have VE.Direct for simple things, VE.Can for expansion (if needed) as well as Bluetooth for wireless connectivity.

Thanks. I appreciate that you have responded to a couple of my questions.
