A good deal for the panel alone, as 100W units usually go for $100 and more. The included charge controller doesn't appear to be a good one, based on the reviews, so view it as a throwaway freebie you can replace with a decent one costing $10-$50 (eBay's got some deals on them).

What I'm wondering though is what kind of battery to get with it. Deep cycle, I'm guessinig, but what capacity? Does HD even sell those? And what about one of those mega power banks marketed as power stations, which are basically high-capacity LiOn power banks that look like SLA-based car jump starters? Those have built-in USB ports and AC inverters, and IIRC some even include charge controllers. There was a deal here on one of them recently. Might be a good match.

I meant this sort of device:

What is the typical application for this? Recharging a car battery or lawn mower battery?

Powering something remotely. I want to power some outdoor cams.

You would def need a deep cycle. But really you could use almost any deep cycle. A typical car battery would do fine. I have one that keep as a spare and the trickle charger can charge it at 750 mah. This one can produce 8ish amps so I can imagine with light use you can keep it charged.

Example use. Emergency power for your router/cable modem.

You could also get 2 of the ExpertPower EXP12200 from Amazon. And put them in parallel. They will handle 6amps of charge so to be safe use 2 will fall under the 8ish amps this can provide at its max(which may never occur)

Aren't most car batteries non-deep cycle, making them a poor choice for day to day storage of surplus solar output for later use with an inverter or DC devices? And, those increasingly more common LiOn-based power stations with built-in charge controller and inverter seem like a good match for such a panel instead of a deep cycle SLA battery.

In any case, this is more of a curiosity thing for me now as I have no easy way to mount one of these where I live. We get decent sun, even in winter, but it's a rental with a slanted roof oriented EW so I'd probably have to install a mount on an exterior south-facing wall, which the landlord probably won't be too happy about (although there is a perfectly located air conditioner that's rarely used that might make a good mount). More of a longer-term project.

In the meantime, I am actually building a simple car battery solar trickle charger/tender, consisting of a small solar panel I built out of individual cells, that should get 6-8W max, and a 10A PWM charge controller to connect the panel to the car battery to avoid overcharge and discharge. I'm now trying to work out the wiring scheme from the panel to the controller and from it to the battery. I want to make it modular so it can be disconnected easily, meaning with some kind of plug/jack connectors. But even with such a modest power output it should be able to keep a car battery topped off if permanently connected.

I suspect remote/off the grid uses, like RVs, hunting/fishing cabin, boats, car camping, picnics, day at the beach, etc., for charging phones, tablets, powering a small TV, DC lights, etc. It's overkill for maintaining a car battery and underpowered for home use.

This is a good deal as for as I am concerned. Harbor freight has their 100w setup on sale for $150 and has a 25% off coupon also and that only drops it to about $113. So this is a far better deal. So I ordered 2 of these to use with deep cycle marine battery and my 1500w inverter.

That answered my question regarding the HF panel.

Total solar noob here - how standardized are the interconnects for this stuff?

Thinking of using this to keep a deep cycle charged during a three day music festival, and maybe a sailboat or RV in the future.

Read the question and answers under the panels on the homedepot site about the connectors. I went through some of them for answers.

No, most car batteries aren't deep cycle, they're optimized for starting. You have to specifically look for a deep cycle battery.

A lot more marine batteries are optimized for deep cycling, but there ARE marine batteries that are also optimized for starting.

I'd also spend the extra money and get an AGM deep cycle battery, but it all depends on the usage and where you're going to charge it.

Your right in my case I am using a car battery as an emergency router power supply. In this application is it safe assume that the car battery will not last because of the constant charge discharge? Assuming you are getting fairly good sunlights

Quite a controversy on this device.

Jackery changed the specs from pure sine wave to modified sine wave during the sale. I'll be returning mine.

For anyone looking for the information, this has SAE (AKA "Z Amp", or "Flat-2") connectors. In some applications, they seem to be superseded by "MC4" connectors. YMMV.
