I edited my first post. See above.

I have been searching for flexible solar panels for a small electric boat project I would like to build. It appears most of the flexible panel sellers out and out lie about the panels output. They claim 100 watts-200 watts for panels about 26" x 44". To me those ratings are totally impossible...

Here it is a year later and my NOCO lithium iron motorcycle battery is still starting my MGB with no ill effects using a 63 amp alternator.

Ha ha!!

My transfer switch is inside the house right next to my TV so it is no problem to switch over. I also have a switch inside the house to turn the inverter itself off and on. My home made transfer switch completely isolates inverter supplied power from commercial power. It switches...

My SCCs are 12 volt. I really don't want to replace them as long as they are working good. I wish I had read up more before I started this project. I didn't know about this forum when I began this experimental journey. If things break down, I may rethink everything and do things different the...

I live on 10.5 acres so I have plenty of room. My charge controllers and batteries are inside. I have 4 x 100 watt panels and 2 x 180 watt panels. The job my system does is run my stereo, TV, laptop and internet modem and equipment. I have a manual transfer switch to go between my 1200/2400 watt...

I have 760 watts of panels using two 30amp Renogy PWM charge controllers. The boost charge voltage is 14.2 for lithium iron. I'm running 4 x 125ah AGM batteries right now. I am thinking about maybe a separate system for the Lithium iron battery to start with. I live in Florida so freezing is a...

I checked. My solar charge controller has lithium iron settings. Should be an easy change over.

Bought my first lithium iron battery. I am using agm batteries in a small solar system. I am curious about lithium iron batteries in solar so I thought I'd get one. I found a 100ah Chins 12volt for $309 and that seemed like a good price. I have seen video on youtube that shows the Chins battery...

None of these concerns worry me in my application. My NOCO Lifepo4 400 cca battery is in my 1974 MGB. No "electronics" to worry about and since it is set up as a fair weather convertable, I won't be starting it at below freezing (it does actually freeze here in Florida on occasion). It does have...

Thank you all that responded with helpful information. Will eventually be adding some solar. I have a small solar system at home that I run my computer, TV and home stereo on using AGM batteries. I will be going Lifepo4 when the AGMs at home start dying. Now that lithium is getting cheaper, I...

Well alrighty then. Don't bother.

Any one use these Zooms Lifepo4 batteries that Walmart sells? Just curious. Considering on my camper with no solar.

Use it with your extra batteries to power your water heater.

That mount looks like the wind may spin it around. I can't say what will work in your area. I live way out in the woods and the county doesn't seem to care much about my system as long as it is stand alone. Here is a pic of my inside panel. I have a single circuit from the inverter to my...

I can't answer that question. My system is isolated and dedicated to running a TV and desktop/laptop computers. No grid tie.

Posts and 2x6's

I wanted to build a system to power my laptop, TV and music computer with 32" monitor, stereo amp with four 10" 3-way speakers and my DSL modem so I would still be in contact during power outages. I started with four Renogy 100 watt panels, 2 Vmax 125 a/h batteries and a 30amp Renogy Wanderer...

Forget the 12volt battery and just go with 24 volt lights.

I use a LiFePo4 motorcycle 400cca battery in my 1974 MGB. It is in the cockpit so it doesn't see high engine compartment temperatures. Works very well so far. Been in the car a little less than a year. Spins the 1800cc four banger over really good.

Glad I ran across this thread. Somehow I missed the need to fuse each panel in multiple parallel circuits. I have been running 4 x 100 watt 12 volt panels for about a year. I ordered 4 fuse holders after reading this thread. I have one fuse on the circuit now. Learn something new every day if a...

I would go for natural gas as opposed to propane. Cheaper for sure. Work on your English. It would make your posts easier to read.

The way it's wired now is how it would be in a stand alone off grid solar system. It is totally isolated from anything in the commercial power system. I'm going to leave it this way.

That is what I HAD. It is no longer what I have. I no longer have my inverter tied to a separate grounding rod. My equipment ground on the inverter circuit now stops at the inverter. I switch all three (hot, neutral and eq.ground). My 120 volt receptical is now completely isolated from the...

Got me a 30 amp rated drum switch. I am now switching ground, neutral and hot on my 120 volt circuit. Position 1 is commercial power, center is off, position 2 is solar. Solar is now completely isolated from commercial power. Everything I want to power is now connected. I've been running...

Don't know about the video you speak of. Can you link the location of it?

From my inverter manual: "6. CONNECTION 1). Grounding The power inverter has a terminal on the back panel marked "Grounding" or " ". This is used to connect the chassis of the power inverter to the ground.The ground terminal has already connected to the ground wire of AC output receptacle...

The diagram I referenced came from here. Grounding Made simpler - Part 1: AC/houshold grounding 2021-01-22 here:https://diysolarforum.com/resources/categories/beginners-resources.10/

That was what I was thinking until I ran across this wiring diagram. I haven't hooked the commercial power up yet. Just using the inverter off my small solar system. I will look for a three-pole manual transfer switch before I go any further. Thanks

So fig. 2 is incorrect?

The wiring method I used is "separately derived source" (fig.2). The only difference is that I have a standard receptacle in place of the sub panel. My inverter is also grounded to the solar system earth rod and my inverter connects ground and neutral together inside the inverter. Am I still...

I have a 120vac inverter from my solar going to a dp on-off-on manual transfer switch. The commercial hot and neutral are isolated from the inverter hot and neutral. The output of the switch goes to one 120 volt receptacle that my computer plugs in to. My question is should I tie the ground from...

When I say a 15 amp circuit, I mean the the wiring is #14 that would be rated at 15 amps for a 120volt ac circuit. I will never have that much load on this circuit.

I have four 100 watt panels paralleled on one (25 amps) and two 180 watt panels paralleled on the other (23.5 amps) The two controllers are hooked up parallel to the batteries. All the batteries are 125 ah batteries in parallel for 12 volts at 500 ahs. Two controllers so I don't overpower the...
