DIY portable solar panel mount

What about a set of "rabbit ears" from an old TV or TV antenna? With two sets you should be able to use them to prop the panel, depending on how heavy it is and how substantial the antennas ...

Should I expand or duplicate my sailboat solar array?

Depends on the controller type. If you have an MPPT controller, the rule is that panel series voltage needs to be higher than battery voltage. Also there may be max panel series voltage. An example: ...

What's the proper cable to connect this power station to a solar panel?

If it's a standard plug it seems likely to be a "2 pin cannon female plug" similar to this, but with the two pins in a slightly different position and a screw lock. I see variants online ...

Short Life of a Battery in a Solar Cell Garden Light

You haven't diagnosed the problem yet. The problem isn't necessarily battery life. It could be available energy. If the solar panel isn't big enough, it's very likely that after a cloudy day it hasn't ...

Smaller 800W Off-Grid Solar Panel System Arrangement

I don't see any problems with the way you want to connect your panels, if you have the cables and interconnects sorted out. If your max power point tracker is like the Epever Tracer4210AN, that big ...

Smaller 800W Off-Grid Solar Panel System Arrangement

Your plan seems very well researched. I agree with Juhist that it's best to push the battery voltage up to 48V since you're only using it to run an inverter. This will dramatically reduce wire size ...

Smaller 800W Off-Grid Solar Panel System Arrangement

This looks like a perfectly valid diagram for a working off-grid solar system. However, several considerations: Are you really sure you want to use a 24-volt system for 3000W? I would heavily ...

Can I use this "hydro" inverter with solar panels SMA hyroboy HB 1124

Maybe, but you need to look at V_DCmax, V_DC and I_DCmax specs of your unit. If you exceed any of these with your solar panel, for example due to open circuit voltage exceeding V_DCmax, it won't work. ...

Should I expand or duplicate my sailboat solar array?

If you look at the datasheet of your MPPT solar controller, it will tell you how much Wattage it is able to handle. If this is the controller you are using (https://www.newpowa.com/products/30a-mppt-...
