5500W inverter if pulling max current on a 48v battery is approx 115A - well under the 150A rating The BMS overheating may be poor connection or undersized wires connecting it to the loads. The breaker tried to trip, but fused closed - so something pulled higher than normal current, and once the...

It Depends: My system runs my business and my home next door, typically the overnight draw-down on my 99.6kWh ESS will be 15% running both properties. If you have three days of ESS available, then any one day is about 33% and depending on what runs at night you may use 10-15% overnight.

Nice spot! Seems Aus has a good network of installers for a dollar per watt, see who is in the area? Remote enough the rules don't apply???

Yeah, I figure since the 6Hp Air compressor cycling doesn't dim the lights like the DeathStar powering up, then all must be ok in the Solar Power Plant output.

I will chime in, I got my first 100Ah server rack from Sig Solar, it is a good battery, but cost me quite a bit more than the second 100Ah server which I got on a pre-order from Solar Parts Store (Orangeville/Barrie Ontario). Things have changed quite rapidly since then (2021) and today you can...

Interesting, but we don't really know unless we measure it. In my set up I am running three low-mid-tier MPP HF inverters in parallel. The inverter set up was/is for my business really but since it exceeded my expectations, and was just too much fun, I added in my home which is next door. Now...

You stated "it is hard to get a good stable waveform". I thought this may mean you have an Oscilloscope to track the waveform - to know it is "not stable", otherwise from where does your comment originate ? I have a picco scope for working on cars and tracking down ignition problems from...

With utility rates (likely) increasing, the payback will be even shorter. (y)

do you have a scope to illustrate what you mean? - curious, since I am running a lot of motors on HF AIO's.

People have been through a lot in the last few years, a pandemic, jobs affected, then we got past the pandemic but supply chains continued to be an issue, then inflationary pressures, rising interest rates and world political unrest/tensions. It is unsurprising that sales of an expensive new...

NICE! Hope the roof is not too high up...and hope it is shingles not metal roofing !! For all the talk, I really don't think it matters that much, as long as the in-rush current is within the limits of the inverters. My HF inverters just hum along running shop equipment, Elect Dryer elec HWT...

or see where the Hertz EV's are going to auction - if they are selling off a significant number, maybe you can pick one up for low cost, and low mileage?

I recall the fuses are in a few sizes based on their capacity - ie the 100 - 200 class T will not fit in the holder for the 225-400A class T because the fuse/ holders go up in size with the amperage.

I do this as well. Mostly due to the northern lat / crappy overcast Nov-Dec period. Converting to USD I pay a minimum monthly charge (ie if zero kWh used) of $25 USD for the connection. As you say low cost back up system - doesn't take a lot of fuel in a generator to be at least this amount.

$20/mth? If the average home is using 1,000kWh per month, at an average cost of 15-cents per kWh - isn't this 150 per month? (and then again a lot of homes use more than 1,000kWh per month running A/C) Maybe I missed what you mean?

We see auto dealerships do a 'facelift' every five years it seems - lots of expensive components just to freshen up the look of the buildings and look 'new' again, spending a lot more than a few hundred thousand ...they don't seem to be losing money.

"This AIO is only 285 (plus shipping)" Correct - I bought all five of my MPP's from Maximum solar. Legit.

I disagree - the FLA (full load amps) may be considerably less than the in-rush to start up the freezer. Typical motors can be x3 or more the FLA rating for in-rush upon start up. I have a Kil-o-Watt and an In-Rush meter, my own freezers draw close to 20A to start, then drop down running. My...

Knowing the rules is key. I know a guy who wanted to build a simple small place - he lives alone raises some beef cows and does 'horse farming' ie pulls a 140-year old plow with a team and plants all by hand and likes it that way. Yeah he is old retired guy and not one to chat much. So he tells...

Wow!

15,4 + 44 = 59,4kWp PV :love: :love: :love:

DC inside a structure Only in metal - ie in metal trough or conduit or metal clad cable.

From the first pic - put drywall or cement board behing all the electrical gear over that plywood. Not sure if this is part of your NEC but in my area no DC in the same trough as the AC - separators are allowed but this still didn't work for me as the wires need to cross somewhere to get to...

I got an old wood-stove free for picking it up, and bought some black stove pipe. Hooked it up and got some HEAT into my Greenhouse since it is still below freezing at night where I live...in the North-woods. Now if there was only some easy way to trade my problem with @BKY2003 's we could both...

We are the exception in my area, bought the EV used. Wired up EV charging to allow dump load in summer or switch to utility charge for winter. A kWh of solar (for me) equals $0.71 of 'not gas' transportation mostly due to living in a place where electricity is hydroelectric ie-cheap, and...

SOPPRESSATA is ready! (and turned out very nice this year, good dry January).

Nice. I have similar ideas for my own MPP inverters - to be repurposed one in the Greenhouse, and one in the Barn, one for my remote cabin. each one is 120/240 so that is a nice plus, at least for small-ish loads. The only drawback being more batteries, but I fully expect some great new...

Seems a lot like a digital camera making a shutter sound...?

100 feet of direct bury cable in tough ground...now I need to up-size...should have used conduit. Crap. :fp2

Same - there are things a 2500 Ram can do that a Kona can't. But general trips to the City and picking up small items are fun in an EV if she lets me take it for a spin. - I thought the "EV Grin" was from driving to the City and back knowing the car was charged from Solar dump load. ;)

Welcome to the DIY Solar Forum @JuiceBox - we see you are new to solar, will try to help you learn a few important aspects: Your first appliance running off grid. From your photos, you have two parallel 12v 150Ah LFP batteries: together these batteries are 300Ah (300 amp-hours) and since they...

Yup, without fail, I wait 7 months to get a V1, and a month after I get it - a better deal appears! (a second V1 would be a good thing to have :unsure: ) don't spend any money, don't spend any money, don't spend...
