I think I’ll just use extension cords from the inverter and play it safe(r).

Hello all, I've been shopping around a bit and ran across this from Battery Hookup and wonder if this is a great deal or should I wait and shop around more as prices continue to fall? I know its a gamble just asking what the consensus was (if there is one). I am in no hurry am thinking about...

No RF interference. Made contact with an Australian station 8,000 miles away.

Back in July 2019 I created this small setup to power my 12v Ham radio station. At the time I had one radio which consumed 1amp on standby and like 7 or 8 at full power (100w) transmission. I was using the radio a few nights a week for about 4-5 hours and only transmitting occasionally not all...

VOC is a characteristic of the panel such as 400w. Many 400w panels have VOC in the 40-45v range. And you want to leave some margin so you don’t fry your expensive Inverter. Thus 3 panels in series (3S) is ~150v. Make two of these and connect them in parallel (2P) for the same 150v, double the...

I will start the build as soon as I get the batteries.

The Eco Worthy ones on eBay are $368 with coupon through 2/19 and free shipping from Los Angeles which is near me. https://www.ebay.com/itm/126141151527?var=427139906179 Michael

I ordered the MPP LV6548 250v version from Watts247. Gonna read the manual again and start collecting the other stuff I need (besides a battery and solar panels). Should be fun!

What did you order and from whom?

@littleharbor2 Thank you very much. Looking into it now. Michael

Thank you!

Bummer my Siglent only goes up to 32v. Oh well I will wait.

On the right side, below the buy it now button, there a small bit of text that says “From only” and a “show me how” link that gives you the coupon code “PRESIDENT20”

Batteries are kept in large vented space under the main floor so no issues with outgassing. I got out of ham radio after 8 years because I had accomplished what I wanted. I still have some equipment however not getting on HF anymore. It was very fun for the first few years then it got a little...

Need a better photo of the cat 😻

I’ll bet a quarter they’ll have more soon 😀

Repurposing my 12v system is not viable. 12v lead acid batteries are not well suited for a 1500w 120v application. My charge controller can handle either 12 or 24 volts so that’s out of the equation as well as I want to create a 48v solution. I’m left with one solar panel to repurpose and that’s...

I think my Siglent will do two channels in series so I may be able to hit 51v... gotta test this...

I've watched the video that Will did on this system a few times and it looks like good for my needs - power a 1250w portable air conditioner in my work shop this summer. Question: Is this still the "best" way to go with the EG-4 3000EHV-48 and EG4 LL 48v 100AH Battery? The AIO Inverter seems...

https://maximumsolar.online/product/lv6548v500v/ I’m new here and was looking at the LV6548 and ran across this. Is this the same LV6548 that is so popular? Looks like a decent price. Michael

👍 Wife only needs to run the heater for 15 min in the morning. Now the AC I could run much longer…

I’m looking at the same setup. I’ll be following this thread. Michael

Success! Unit powered up and looks good. Thanks for the suggestions! Michael

15 days. I must be looking at the wrong website/store…

I’m confused. The product in the link says it will handle PV 500v is this a new product variant?

Hello all, Received my MPP LV6548 today and I was wanting to test as much as I could in the next two weeks. However I do not have any panels and I do not have a 48v battery. Would it be a good idea to connect the AC IN line to an outlet I have in the garage just to get it up and running? That...

Thank you for your advice. Are there any of these companies in the Los Angeles area? I could drive up there (60 miles or so) and save shipping. Michael

Yes I know the usual 120VAC space heaters are 1000w-1500w which is a huge energy suck however they make 12v "car" or "truck cab" heaters that are much less watts 150w and up. I was thinking about getting a 300w one and try it out to see how well it would heat a small bedroom and go from there...

It appears that my biggest obstacle is my 12v setup. If I wanted to power a 1500w space heater my inverter would draw 125 amps to generate 1500w at 120v from my 12v batteries (did I get that right?) which is pretty much off the charts. So I want to think outside my existing 12v setup. Let's say...
