Personally, I think this video could have been packed with more information that actually compares both types of inverters while mentioning the features and qualities of the inverters displayed in the video - are they strictly grid-tied, they don't seem to have battery terminals, only PV input, at the DC end or something. Moreover, I have read how that people believe that the LF will totally outclass and outmatch the HF inverters, and even be more durable. However, I dare say that these opinions are based off of limited experiences with premium HF inverters, because they can be cheaper to construct, and can be constructed in multiple ways since they employ circuitry to achieve power inversion, there are different quality forms available with most people procuring the cheaper and less premium variants.
Maybe worth mentioning the efficiency difference between them, also? The high frequency inverter should be more efficient, by more than 20%, right? Tank you for the insight, all the best!
Solar is so wonderful and is very similar to factory floor inverters. Just need to get people acquainted to the solar arrays. AutomationDirect has several FVD DIY videos. 😎 Thank you. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-XuamHrTXfU0.html
Is the first diagram showing th3 PV ground rod connected all the way to the house AC ground rod? Is it not best to Isolate the DC and AC grounds so as not to create a loop?
What about grounding solar and INV via the copper water pipes which are naturally grounded as they run underground...this in combination to the main and critical load panel which are grounded via a 8 feet copper bar ?
Bogus review...no mention of battery connections which are vital to function. Inverters in this range do not rely on pv input to make ac current. Also no mention of advantages of low frequency inverters over high frequency ones other than a mere mention that they are 'simpler'. LF inverters tend to handle motor start up and other momentary high loads much better than HF inverters. Plus they tend to be much more reliable with all the simplicity. This review really doesn't shed any real light on comparison of LF vs HF.
I do understand your first point (about the batteries) but calling it a bogus review is a little over the top. He reviewed two different types of transformers from manufacturers, ones which don't seem to have terminal inputs for a battery. Of course, the video could have been made to be more informative, listing some of those points you have mentioned and even more.
how is it being heavy a problem ? Its not like your going to carry it once a day somewhere , Its stationary !! The low freq. inverters are much better for starting well pumps or anything with a heavy start current ! And they last much longer than high freq. inverters . After what I've learned the past 10 years from building solar systems , I wouldn't even consider using a high freq. inverter for anything . They are simply a cheap option really .
I have a question, I recently purchased an aims split phase 240v/48v inverter charger. I powered up my up right garage freezer with it, but it gets extremely hot. Not sure what could be causing it. I did buy it for taking a few circuits off the grid, I'm just testing it for now.
It could be but also from my experience I would say that you're losing more than 20% of your energy because of the loses, on the low frequency type. I would go for a good high frequency and good quality inverter, and for the well pump I would put a slow start, inrush current limiting module. This will also prolong the well pump life. On more than 15 years working with them, I would definitely go for a good high frequency type, no doubt of it. I've learned my lot of lessons. But you definitely have a point. Those low frequency inverters are very reliable. Still, with the actual technology I'll always say that isn't worthy anymore. Cheers!
I don’t think is totally like you say . 1) toroidal transformer inverter are much more efficient that real LF, that have a square iron transformer. Almost like HF. 2) they’re companies that produce both and absolutely recommend LF for repeated high surge inductive loads. They explain specific in they’re sites. I have a doubt. Victron energy call he’s toroidal “hybrid HF” and not LF. Why?
One important point that is not mentioned is that the ground rod will only cause a ground fault if it's impedence is lower the about 8 ohms. 120v divided by 15 amps. Most grounds don't meet that requirement. The ground is only there to sink residual voltages and of course a lightening strike. It's your neutral that returns the current to your source and your ground should be bonded to the return path for it to trip your breaker.
I have a question I am not from your country so not sure how many inspection you have over there I hope its not the only one. Because there is a lot of things you just did not. What about measuring? There is a lot of stuff to measure... what about thermo camera check?? And it looks like you only look into a boxes just like from the train pasing by :-))) What is this all about????????
Stop it - NO NO NOI~, Here's some Non Grubbermental Facts ---- Do not "ground" your solar, your inverters, or your controllers. NEVER give outside static or current a route near it. There's only ONE WAY. The NEC Code folks are morons. Leave it all floating, But you must Quasi Faraday isolate it. It has NO need for earth ground, WHY??? Its not originating from a line energy generators, Has no actual Common Line energy like a utility, Has no originating Phase to Ground path. Those lightning arrestors are freaking snake oil, you just Create a lightning collection system of peak rods near your system. At least 20 feet away and 10 feet higher with at least 8 feet in dry soil, or 4 feet in moist soil. These solar EMP and Lightning Arrestor sellers are scam artist. High volt DC output is NOT going to Blow Your Arm off between you and the ground if it is NOT already grounded somewhere else.
Plastics compress with mounting hardware. Aluminum frames may be superior to plastics in expansion, extreme temperatures, cracking and ability to handle heavy snowfalls.
1. Add additional batteries, keep batteries charged to a healthier level, 90% etc. Use the 10% for a buffer. #2 use heat pump water heaters, wire the coils separately from the heat pump. Use the water heater coils to burn extra energy. Each has 1 heat pump and 2 coils so there are 3 levels of energy you can burn. And if you switch coils to different watts you could have many more levels you can burn. Keep the hot water heaters lower temp and have 2 or 3 instead of 1 for normal use with a temp mixing valve. Have the excess power heat to the tanks max. Use a recirculation pump to loqer tank temps if they max out. Think radiant floors, driveway, garage floors if necessary.
now this problem has been sloved ,battery inverter will communicate with pv inverter and tell it to decrease power when there is excess ac power in ac bus side in the case of grid is fault
