It would be nice to see some stress tests of this inverter starting inductive loads. I had a Gandel 24V 4000W inverter that went off like a string of firecrackers when I ran a non-inverter 12K BTU air conditioner. I had run that AC on it several times in the past, but that day it decided to fail. It blew traces off the pcb, so no just replacing some blown FETs. I bought the 24V 4KW vesion of the SunGoldPower inverter, but have been afraid to plug my small AC into that for fear of blowing it up.
Deeply appreciate your clear breakdowns and explanations. SGP inverters have recently changed and am hoping you can enlighten us. There is a green grounding pigtail for automatic neutral-to-ground connection. Mine arrived disconnected, yours was connected. I'm using mine for a home sump pump battery backup. SW3 use to select 3 or 30 seconds for power save mode load detection. Now it has 3 second and "night charger function". The manual has no information on "night charger function" and my tests appear to indicate that it no longer is the 30 second load detection. Appreciate if you can clarify for us.
This device (in various brands) has been around almost unchanged sine the 1960's. It was designed to last forever. You see these mounted on heavy equipment all over the world that have been abused for years and still work beautifully.
Aims, Sigineer, and Sungold all look and seem the same, aside from a few auxiliary functions. The big question is who offers the best service and support?
Thanks for the review Tom. I just bought one and will be hooking it up. I have an off-grid cabin in Alaska and been solar powered battery bank and inverter powered by generator for AC. I’m building a shop and putting in sub-panel to isolate either cabin or shop. Will be interesting to see how this bad boy does when air compressor or heavy power tools load it. Thought it would be a good option to divert all power to the shop by isolating cabin if I have heavy draw going. Like your style BTW!
1200 watt daily standby consumption is a lot. I only use 1500 to 200 watt a day. You’d probably want a battery bank if 20kwh or more. Good device, but not for mobile application
It uses 15w in power saving mode. I have to use regular mode in my RV since the inverter goes through an auto transfer switch and in that case it does use about 100ah a day at idle.
Thanks for the great review. This inverter ups charger looks great, with my 2 concerns being the charger and the warranty: As the commenter Snow100ball mentioned below, it would be a much better deal if it had the DC/"solar" charger and not just the 120VAC charger. If it is "better" quality, why don't they back it up with a 5 year warranty?
Thanks for the very good information! A quick question, it named "Charger", I presume that means charging from 120V outlet. For solar charging, I still need a separate MPPT charger, correct? Also, its the remote control panel an optional or it comes with the unit? Also, can this unit starts without AC 120V input? I saw on their website, the unit "Require AC120 Input", I'm not sure that means only the charging function requires AC120V input, or the whole unit needs AC120 to start (power on). Can it cold start on battery? Thanks!
@@HOBOTECH One simple thing you could do is take an small AM radio, tune it to a Low spot on the dial where there are no stations and Hold it next to the inverter to see if you get noise when you turn it on. Almost like your Audio Amp test. We used to hold the am radio next the the PC's when running programs to see what sounds would come out.
. I belirve that is what they were talking about at the solartech group ,,,link I tried to post. I could be wrong...not first time, surely won't be my last😁
We have power outages here that last for days. (44 hours last winter). Will this unit automatically switch to charging with solar panels when the grid fails? Do I need a separate charge controller for solar panel charging? Does it do "pass-through" charging when solar panel charging? Thanks.
Why have the option of how many amps to the charger? Wouldn't you just want full power charging the batteries all the time? Or is it based on how many batteries you have? I'm confused.
@@HOBOTECH MMM. I have a lot to learn. I bought a DC refrigerator a few years ago, but my lead/acid couldn't keep up. So i just bought two 200ah liTime lithiumPO4 batteries. Now, my challenge is a charger and inverter. I have a 50amp service fifth wheel, so I am considering the Sungoldpower unit you are speaking of in this video. I have no solar and don't intend to go off grid. I want a system with a transfer switch, charger, and inverter to handle my DC refrigerator, a few lights, a TV, and maybe the air conditioner during lunch while traveling. To have the inverter handle the full 50 amp, I'd need a 6,000w inverter and most likely more batteries. But I'm not trying to go off-grid. I want a unit that can handle a few things on our traveling days and not have the refrigerator die at the end of the day. Do you know if the unit above will solve my issues?
Thanks tom. One thing caught My Eye on the Spec Sheet You put up. It showed Pure Sine wave in bypass mode only ? If You can clarify Thanks Much Mike M.
In Parentheses ( ) it states pure sine wave in by-Pass mode only ? I'm thinking by-pass is the Grid side. UPS is from the inverter. Does that mean this is a modified sine wave from the inverter ??
So my question, is the inverter/charger does it only charge Via grid power only. Will this accept solar panels with or without a charge controller? We have a chicken coop that I want to run solar first with a grid backup. As always thank you for the great content and my wife thanks you for spending our money.
This model does not support solar panels. If it did I would have certainly talked about it. They do sell other models with MPPT built in. gohobo.io/sgp
@@HOBOTECH so, are you saying this unit needs external MPPT charge controller, for solar charging. But WAIT, therrrrr's Morrrre... This unit needs to be hooked up to a battery bank, to have power,,,so, , , does its internal charge function charge the batteries it is hooked to, and gets its power from?😶 ,,,sorta confusitating⚡👀⚡
So you can save a ton of money, easy expansion that's cheaper. Better solar wattage/volt/amperage intake. That's why I built my own mobile power stations. I can build 2 or 3 stations for the cost of a eco flow delta pro. It's got more capacity, can handle 250v-500v of pv input. Very few power stations can handle that. Yeah it's nice to just plug and play. But you pay a high price for that. No thanks.
If you want 4000W do yourself a favor and go at least 24v if at all possible. 48 even better. Do you really want to mess with cables/connections that safely support over 300 amps or current?
@@HOBOTECH I get the RV thing, but it's really a function of the panels if you're doing solar. If you can do over 24 or 48V then it's easy to supply 12V with either. Any way you're talking a 120V AC inverter. Much better starting with 48 or 24. Just my humble opinion. But everyone's situation varies. Options are good. I will say I started with 12V inverter but quickly moved up.
@@stevenlouis1024 Sigineer is apparently the OEM. We can only guess about parts interchangeability. Pricing seems AIMS>, SGP=Sig. Hard to tell with the opaque nature of Chinese industry. I went SGP if only for their more active nature.
Some reviewer used an oscilloscope to show the output wave, possibly Hobo on the 3000W version of this? Breakdown occurs at higher wattage, as expected. It would be interesting to see THD vs W.
Not the end of the world. Typically cables are short between batteries and inverter so you can use 2/0 up to about 6ft round or 4/0 if you need to double that.
Mr Hobo, respectfully this is the first video I’ve watched of yours and came to post the same thing. It was not mentioned in this video. I am specifically looking to power a rack of home server equipment with this. Thanks!

Do I have to switch off inverter before I change? Dip switches from AC power to battery power?
Why have the option of how many amps to the charger? Wouldn't you just want full power charging the batteries all the time? Or is it based on how many batteries you have? I'm confused.

Yes inverters need hooked to batteries. Where else would the power come from?
@@HOBOTECH chargers normally plug in to 120v AC power.
Invertors connect to batteries, to make AC power.
Title and thumb says INVERTER CHARGER. What would the charger charge except batteries? I'm obviously being trolled.
Why would you select an inverter like the Sungold vs a Solar Generator like Ecoflow, Pecron, Bluetti,etc which has the inverter built-in?

Doesn't work with a transfer switch and there is a delay with the inverter starting up in eco.
