    Occasional 3-phase

    Go to Ebay, you can pick up a suitable VFD for $100-$150, it will work great. I use a bunch of them around the shop as 3-phase motors can be had dirt cheap compared to standard motors, most people don't want them. For applications using variable speed and a ton of low speed torque, you can't...

    finally bought solar

    You're not in the US are you? That inverter says 230v AC, which often means a single phase 230v such as is used in other parts of the world, not 240v/split phase as we use here.

    The more I research the more confused I am.

    Before you make decisions look at an annual solar irradiance chart for your location. You are so far north that you're going to get very little solar input in the winter compared to the rest of the year and you'll need to size your panels and batteries to allow for that. I'm a lot further...

    Alberta Lithium 12v 100AH battery teardown

    Not sure where you got your definition of "sponsored", but in the rest of the world if someone gives you a free battery and you put up a big post telling what a good battery it is, that is a "sponsored review".

    Beginner solar setup

    I've had a Truckfridge in my van for years, it's a 12v Danfoss compressor fridge, does a fantastic job. My original solar setup was 200w of panels and a 150ah lead / acid battery, it ran the fridge and lights just fine. I spent 2-3 months a year on the road living in the van, camping around...

    Its time to talk about the mighty Hysolis Apollo platform all-in-one solar generator.

    Is this a good deal?

    Santan Solar has an outlet in Georgia, you can get 250 watt panels for less than $50. I've got 40 of them, they're working great. Look them up.

    What makes the tier 1 stuff “better”?

    To answer the OP's original question, what's the difference? Ask anyone who has had anything manufactured in China. You work out the contract, agree to terms, take delivery, all is good. Next shipment you notice that the capacitors you specify have been substituted for cheaper ones, contract...

    Sungoldpower BUYER BEWARE SP6548 DIED after just 6 weeks, another scam victim of sungoldpower F90 code is flashing and shuts down

    Sounds like time for a call to the credit card company for a chargeback based on not receiving what you ordered.

    Freeze-ageddan oops

    My solar power system lives in my shop. The solar is in a small room, 8' x 16' with two inverters, four 16 kWh batteries and three solar charge controllers. The room is well insulated and the waste heat from the equipment is enough to keep the room in the 50's even when it's well below...

    How to handle freight delivery?

    My most recent load of 40 panels from Santan looked perfect coming off the truck but when opened the bottom panel was very broken. I sent them a picture and an explanation, they credited a refund to me that afternoon. No hassles, excellent people to do business with.

    maybe the most newb question ever

    Just one comment. I see you're in the Portland area, I'm just a bit south of you. Have you looked at the solar irradiance numbers for the area in December-February? I have almost 20kw of panels and 60 kWh of lithium batteries. They run my freezers and shop just fine in the winter, but that's...

    New updated bms app from Overkill Solar.

    I've got 5 of the Overkill BMS units, the new app doesn't detect any of them, the XiaoXing works great.

    Cheap System Help Required

    Just keep in mind that for the next few months you're not going to be seeing much sun, your system will be doing well to generate 1-2 kWh per day until Spring weather rolls around. I have close to 20kw of panels in a similar climate and average about 2-4 kWh per day in December and January.

    Yield with low irradiation

    That's assuming it's not cloudy. Where I live the winters are cloudy, I average about 10 per cent production compared to the rest of the year.

    12vFacepalm

    Look up "sunk cost fallacy". You're getting ready to waste tons of money and time going down the wrong path because you bought the wrong inverter. Return / sell it and start from scratch, write it off as educational cost. Especially for an RV, use quality gear, the cheap stuff won't last.

    Idle Consumption: Is It Standby or Overhead?

    There are higher quality systems with much lower current draws. You pay more, but they're better quality and most likely will last a lot longer, as well as letting me sleep better at night.

    Beginner DIY Roof Top Installation

    That's why my 60 panels are all ground mount. Between difficult installation, chances of leaking roofs, difficulty of re-roofing, etc. it's not worth the hassle if you can avoid it.

    adding another inverter for constant loads

    So what happens to the idle draw on the Growatt when you're not using the inverter? Does it go way down? You need to verify that before moving forward with the plan or you'll just have increased draw, not less.

    Is this solar charge controller big enough?

    On the other hand if you have 1600 watts (rated) of panels it will be rare to see more than 1200-1300 watts of actual power out, so you should be fine. You might lose a few watts at noon on sunny summer days, but not much.

    Good day forum. Help me set up my solar system

    You need a charge controller between the panels and the battery. Don't forget wire and cable lugs, etc. can be a significant expense.

    Questions regarding Solar Panel Requirements to charge LIFEPO4 batteries.

    To answer the question you didn't explicitly ask, don't ever discuss solar with whoever gave you the information you described, it's complete BS. It's clear you know far more than them, they're just misleading you, probably for profit.

    Sanity Check My Vision

    I'm a few miles south of you. Realize that in December, January and February your panels will average at best 10 percent output. Then, figure out how many panels you'll need to do what you're talking about. I have about 20 kW of panels and 60 kWh of batteries, it runs my fridge, lights...

    UK question on winter PV output

    I live in a similar climate, western Oregon, but quite a bit further south at 45 north. I have about 20kw of panels and 60 kWh of batteries, it's no where near enough to heat my small house in the winter. It runs lights, fridge, freezer, etc. but that's it.

    Biden Energy Sec claims Solar Panels 30% Price Reduction

    As a few people have noted amongst the other discussions, the tax credit is "non-refundable", meaning if you're low income it's pretty much worthless. Last year I got about $5,000 in "tax credits" for my solar expenses, I was able to use about $500 of it to offset the small amount of taxes I...

    How do i know the inverter KVA that can power 5 ACs, Tvs and other medium applicances

    So you're in the business of selling solar power systems and your source of information is asking questions on a forum? This is all that's wrong with the solar power industry today.

    Difficult to determine which simple inverter can be trusted in the 2k to 3k range..

    For the best prices on Samlex check out DonRowe.com, they've beat everyone else by quite a bit. I have a 2224, a 4024 and a new 4248 waiting to be installed. Well worth the money.

    Is this a deal?

    Or 310's. The real ones are 302 and 304, from CALB and EVE. If they're lying about that figure they're lying about other things.

    I think I've been scammed!!

    "I've been scammed" and "Aliexpress" in the same sentence, who would have thought it? Honestly the first HUGE clue should have been that they're the same size as your 150's. Efficiency of solar panels varies over a very tiny range. Cheap panels are around 18 percent, the best panels are about...

    How to calculate needed battery size (for only 1 fridge and 1 freezer) to run indefinitely?

    There is no "answer", it's a matter of probabilities since it ultimately depends on weather. Where I live my winter production is at best 10 percent of my summer production. If I want 100 percent guarantees I need an absolutely enormous system. To give you some idea, my first system was 3.5...

    A Question about Lots and Lots of Solar Panels

    They make lots of solar charge controllers like that, just not the cheapest ones. It's basic electrical design to monitor the output current and component temperatures and to limit the output of the charge controller to a safe level. My controllers are rated at 94 amps, they're hooked up to...

    Solar array for 48v lithium setup

    Figuring out your needs is the first step. My 12K BTU Mr. Cool unit runs about 600-800 watts, or about 15-20 kilowatt hours per day. Your freezers will probably average another 5 Kwh, so for a rough ball park estimate you're looking at 20-25 kilowatt hours per day, minimum. If you want to...

    Flexible solar panels on Aliexpress.

    You know that famous quote from Abraham Lincoln, right? "Don't believe everything you read on the Internet." Aliexpress if full of amazing claims that are too good to be true, and most of the time they aren't true. At least in the solar world it's just a big machine to part fools from their...

    280 and larger 320ah cells all seem sto have the same physical dimensions, why?

    The CALB 302 ah cells and the Eve 304 ah cells are real. The "310-320 ah" cells are not, they're just advertising hype. They're lower rated cells being sold at false specifications.

    Trying to decide on a mini split - help?

    I put one of the same units in last October and I love it. I use it mainly for heat. It raised my grid electric bill buy $30 a month, and cut my natural gas bill by $80 a month! Easy to install, pretty old and broke down myself these days.
