I finally load tested my son gold 18 KW inverter. I turned on every Appliance in the house. All four electric range burners, the oven on preheat, the electric dryer, the air conditioning, and just about everything else computers lights etc. The total load came to a little over 16 or 17 KW and the DC draw on the 51.2 volt battery was about 370 ampers. The inverter just chugged along like nothing was any different than the usual. Absolutely amazing piece of hardware.

@@TheVoiceofKevinC If i am understanding correctly, you want to can you use multiple chargers as well as the charge controller on the inverter? If that is the case, then yes- by all means. Example: I use my old Growatt 5k's as charge controllers and have around 500volts coming into the external bus bar from each. I also use 2 additional charge controllers connected to that external bus bar. That is routed to the battery bank bus bar so that all charging is done simultaneously. I even have a "chargeverter" from EG4 connected to that bus bar so I can charge from generator and/or grid if needed. You can multiple charging sources to the battery bank. This then powers the 48v inverter. So in essence, the inverter works off of the battery to create the AC power source seperately from the DC power bank/solar. Hopefully I understood your question.

Instead of your schmancy wirewound 1ohm 100watt resistor you could use a rubber fuse/current limiter, otherwise known as an evacuated, radiant tungsten resistor, otherwise known as an incandescent light bulb. If the device you have seriesed with the lamp tries to draw more than about 100 watts, the lamp comes on full brightness but likely nothing blows up if there is a short, the current is limited to 100 watts. Works great as an inrush limiter. You can also get them with a 60 or 40 watt limit, and they are also available in DC versions with 12v and 5v being fairly easy to find. I used to know the part number for the 12v was it a 5015? With a little bit of practice you can guess pretty close how much inrush current and the running current by how the light looks when you throw the switch. Really handy little device. It is handy to wire one up in a jbox with a 3-way switch, one position your lamp is in series the other position straight through ac. In addition to the visual indication you get, that 100 watt bulb is better than a resistor for what you are doing here because the resistance of the lamp changes with temperature, simple soft start of sorts. It could be that some inverters would recognise a fault on the AC line if you tried to run it with that lamp in series with the ac input so be aware of that.

Now, given these parameters, what method of drying clothes is "smart"er than using stored PV energy? I guess you could say to use the generated PV power directly from the panels (through the inverter) during peak PV power generation, but the normal daily household load might dictate that clothes washing/drying be done late at night, when other power requirements are minimal. I believe this is what David H is getting at: "the personal situations" (the parameters I listed above, or even more restrictive ones) might dictate that drawing stored PV power from one's "very expensive batteries" just might be the "smartest" (or even the *only* reasonable) solution.

Great video as usual. One thing I see is a lack of parallel function. I would prefer multiple smaller parallel hybrid inverters rather than one large inverter. I see that Growatt announced in September (but I do not think yet shipping) a 2nd Gen version of their equivalent of this inverter. It looks like the Growatt SPF 3000T HVM-G2 will start with a capacity lower than their current range. Parallel inverters mean less total failure risk, each one is lighter to handle and needs smaller cables. They too are low frequency inverters, but the 3000 model can handle PV up to 200VDC operating voltage and 80A, so if you have more than one array, multiple inverters give you a lot of flexibility. The AC charger is also relatively (compared to the inverter capacity) large, at 40A. With multiple inverters, you could have multiple battery banks. Growatt have not said whether this new range will use standard laminated transformer (such as the ones you see in this SungoldPower inverter), or whether they will use a toroidal transformer (better, more efficient). But, given that Growatt claim their new product will be 95% peak efficiency, which is much higher than normal (1st gen version is 85% in the smaller versions), it is possible they they may be using toroidal transformers. One can but hope. For now, they are clearly selling off their stock of the 4000-12000 1st gen range (which is their direct equivalent of this Sungoldpower inverter). The 12000 is down to around $2300 including shipping! You also do not mention Wifi (app) control, which the Growatt has an option for.

Quite often neutral is tied to earth at the transformer. So while technically you could use it to power some appliances off grid, I don’t think it would be safe on a typical three wire 230V system.

This is a good point. With modern high-efficiency HVAC equipment, they start up slower and might not be as big of an in-rush. But, air compressors, dishwashers, sump pumps, pool pumps, well pumps, etc. still have high in-rush currents. How do you handle those with a high-freq inverter? Would that require over-sizing the inverter to handle that in-rush load and, if so, wouldn't that consume a higher idle consumption than a smaller high-freq inverter?

@@cuisinartOH1 Some newer HF inverters have a surge capacity of 200% for 5 seconds to help with this. I have a Sol-Ark that is rated at 9kW on grid and 8kW off grid and is rated at 200% for 10 seconds, but still I have seen were people have had them trip on high inductive loads. My inverter has no problem at all starting small motors like the refrigerator, dishwasher, washer, central gas heater, etc, but my shop compressor, I never even tried. Sol-Ark said it should be OK starting a 3 ton AC unit but I think that's pushing it. A reduced voltage starter can be added to AC units like this, and no doubt it would solve the problem, but it cost about $500. You could add these to other motors too, not just AC. One solution is to change the nature of your loads and break-out everything in your house in a separate sub panel to power all your normal loads, put modern inverter mini-split AC units in select parts of your house, and leave the rest on grid. This is what I did and I have everything but my central AC compressor and air compressor on the inverter and it powers everything else just fine.(Sounds crazy, I know, but my inverter and panels are on a coach bus and that's it's primary application and I needed high efficiency but I wanted to use it to power the house when I am not traveling). Another option is to put another HF inverter in parallel to double the power handling for all of your loads. It could be switched on to start high inrush loads and can be turned off to save power once started (as long as the total steady state load does not exceed the first inverter), but that's probably much more money than you are willing to spend. And another option is to use an isolation transformer or an auto-transformer from a 240 volt HF inverter to split-phase. This could help you start high inrush loads, but now you are back to that low efficiency constant waste of power. And if you are off grid only, say hello to your new LF inverter for me. Add the losses to your base requirements and add more panels and battery to make up for it. I guess there's no free lunch. Sorry for the long dissertation, good luck.

There’s two costs here - the initial cost of purchasing more solar and more battery and the ongoing daily cost of not sending that extra capacity back to the grid. The initial cost is probably offset somewhat by the increased electrical installation costs of a separate sub panel (likely to cost a couple of grand) but IMO, you’d be much better off separating out your high inductive loads to a separate sub panel that is grid powered.

I bought Sungold's 6000W inverter for an evaluation project. I have 14kWh or Lifepo4 batteries from Treeline Power Systems. The trick with the Sungold is you must set Utility Priority if you want to run it with utility or generator with the inverter as a UPS backup. Battery Priority position will result in AC ABNORMAL messages and not switching the utility power. If this works out (I have 40 240W panels on order from Santan Solar) I plan to upgrade to triple the batteries and the 18,000W Sungold Power inverter. With 54kW surge capacity, this should even be able to power my 20kW sound system to high volume levels. Getting ready for Biden's Dark Winter and blackout 2022.

The way I have my generator hooked up, is not through this inverter. I have it feeding a second Sun Gold 6kW inverter/charger + a EG4 Chargeverter. So when the generator runs, it's dirty, unstable power does not feed the main breaker. It only charges the batteries. So the house gets clean, steady power from the SG 18kW inverter all the time. The generator adds about 8kWh to the battery for each hour of run time.

Also, could you turn off the battery charge feature so you could connect an external charge controller to your battery bank? It would probably better serve some users. I'd prefer just an inverter and stick with my current charge controller anyhow. The one I am using allows me to charge the batteries off grid (or genset) as well as PV. Doesn't his manufacturer make a 120/240 v inverter? I thought they did. I'd like to see more efficiency when there are no current consuming devices drawing load. Seems this company missed the boat on the charge controller input rating. We are getting closer to really good solar equipment, though.

Put the inverter somewhere that you can heat it up to 120 degF while running it at full rated load. Do this until the inverter reaches a stable high temperature. Then repeatedly hard short the output, say for 10 times. If it survives that it is worthy. And transformer inverters do better on this test than transformerless inverters (in addition, transformerless inverters can fail in a way that delivers destructive high power DC to your loads).
