How many solar 30W Boulder solar panels can you hook up to the generator safely?

According to the Yeti 1250 specs, the unit can handle an max input of 240watts. So, eight 30 w panels is the most the Yeti 1250 can handle....assuming one can link them all together. Just for info, if one did hook up 240 watts of solar panels, the fastest, theoretically, you could charge a very low/dead battery would be 1250 divided by 240 or say 5-6 hours. This assumes 100% efficiency for the solar panels and 100% bright sunlight. Realistically, it would probably take 8-10 hours of bright sun. Sorry.....too much info.

Adding to what others have said, I would go a little higher than the max Amp rating but also limit according to your battery. My unit feeds anything from 225Ah to 360Ah battery banks. If you use the 10-15% of Ah capacity rule then a 30A fuse is fine. I would have to swap in a much smaller fuse if charging a smaller battery bank and of course limit the PV power coming in or connect it to a smaller array.

This is why I hooked my 520 watts of panels in series so you halve the amperage. I can add another 2 panels in the future and still keep it under 30 amps. Remember too that the charge controller can charge a normal 12v battery bank, that's what mine is. I recommend making a 24v panel setup.

You will need a double breaker with a minimum of 25 amp on each side. I have a double 30 on 1 panel and a double 40 on the other (I have 2 hookups) The Generator has its own breaker as well if over drawn.

You can hook up a 30 watt solar panel directly without a solar controller. I posted a picture of my set up in the customer images section. If you had a regular 30 watt solar panel instead of the Goal zero like mine you could skip one of the wiring components.

Sorry, I can not answer that question as we have never used it with a generator.

I have 10 Trojan T-105 6Volt 225 AH Batteries, if you just buy 1kw solar panels then I suggest you use 6 6volts batteries or three 12v batteries

best to use number 10 stranded wire. Most panels have mc4 connectors on them. You can buy mc4 connectors which are pricey @ around $7 each , they are a little hard to connect unless you also buy special crimping tool. cheaper to cut connector off and use wire nuts to wire together make sure hook positive from panel to positive on grid tie. With only 250 watts we are not talking a lot of power.

The charge control can handle up to 7A. Your 30 watt panel puts out ~1.68A at high noon. You should be fine with one charge controller charging two or more batteries and it would require more charge time. Just make sure you hook up your batteries correctly. Personally and for convenience I would much prefer to get two charge controller with two solar panels for the two batteries so that I could avoid having to move and or reconnect the batteries. A larger solar panel can would benefit you quite a bit if you need to drawn power from the battery each night. Hope you are using deep cycle batteries.

Hello Bart. I will recommend 24v battery bank. For simplicity of wiring, I will also recommend 12v batteries. The 4 solar panels can efficiently charge 4 120AH batteries or 2 200AH batteries. Feel free to ask more questions. rgds Emmanuel

Amps=watts/volts. So 250w/24v=10.4 amps. This is considering full output of the solar panel and no loss through cabling. So to be safe you can run three solar panels More than likely you can get away with four, as you will likely never see a full 10 amps output.

I bought two panels, have not installed them yet. Starting out with 4 batteries @ 100 amps, plan on going to 8 and adding two more panels

Depending on what else u run with generator , it does not require many amps when running . A 3kw will be fine Maybe a lil surge when u first plug it in

You can but... For me, the panels are atop a 50 ft tower so I mounted it up there then discovered that when it is not actively generating, it is actually consuming, albeit a small amount, of energy. Therefore, the on/off switch became useful but having it down below would require separate 60+ ft lengths of copper cable. I opted not to use the generator. I installed another panel instead with good results.

Dear David. I have not done so, however the literature that came with mine indicates that you can "link up to 10 panels together for more power." There are however no instructions provided for doing so. My one phone call to Sun Force about a different matter was very responsibly answered, so you might call them. I see there is another response to the contrary by 'Daddio'. In passing, I use the panel and the charge controller that comes with it to maintain the charge in a 12-volt heavy duty auto battery that provides LED emergency lighting for my home. I've been very pleased with it. It would seem to me unless there are other considerations that it would be more economical, and present an easier mounting problem to purchase a larger (more power (wattage)) solar panel to begin with. Hope some of this helps. Randall

How are you going to power it? a generator and if so how many total amps does your generator out ? also how many lights do you plan on installing? Hope this helps

That will depend on how many you are using and how they are configured. Assuming you are using 1 (or any number in parallel to obtain more amperage) any 12 volt trickle charger would be sufficient. I use both a solar and an electric trickle charger myself. Another thing to consider is how often you expect to use and/or drain them. If you are using them for emergency back up, you will needs a slower charger than if you are planning to use them constantly. If these are going in a vehicle, any 2-10 amp charger will do.
