I was doing a reading these past two months regarding the power fluctuations in this area. It's supposed to be 220V at 60Hz. While the frequency stayed between 58 to 62 Hz, the voltages ranged between 170 to 245 volts daily. Unbelievable how wide the gap in voltage.

Thanks for the info. I figured out Gel's aren't really in need of equalization, but I do know that it's an "as needed" kind of procedure. It's just nice to have a controller that has that option as opposed to needing it and you can't do it because there is no option. As I learn more on solar, I am finding little things that I would want and things I'd do differently. I am so glad I didn't spend a fortune and studied things first. I would have made expensive mistakes otherwise. And in some blogs, I have seen people complain about exactly that.

Yeah...I should have toned down the noise. That's not actually the inverter. That was the drill, a grinder and another specialized tool running with a few other little loads as well. They were all running at the same time. I keep it raw as some people think editing removes the "seeing is believing" aspect. Yeah...sorry about that. Thanks for the constructive criticism though.

I absolutely agree with you. Grid is definitely much more consistent "if it is well maintained". I can't say that for this area. It's not just the fluctuation, but pretty sure its not pure sine wave as you can hear buzzing when using appliances that run almost silent on another grid. Additionally the power outages are ridiculous. Two days without power is normal. There are times where five days of no power can occur. And you might have five days of no power, the power comes back and then power outage for two days. Really just ridiculous. Modern does not exist here.

Hello everyone. Made a quick video on Epever MPPT Charge Controller. While going through it I realized that Gel batteries do not have to be equalized. Is this true or should I worry that Epever does not have an equalize for Gel Batteries..? Hope someone can help. Thanks.

Hello. Just wanted to share with everyone this menu programming with MPP SOLAR. I'm stumped at the last setting though. I do not know what it does and, unfortunately, the manual doesn't even have a description of the number anywhere. I'm hoping someone might know what that last item on the menu is. Thanks.

Thanks for all the comments. I figured SOC is different than just battery voltage. I've been studying up on Victron and other brands that offer a bit more when it comes to battery charging. I find it funny that there are many things involved in solar when it come to PV, the inverting itself and batteries. I think MPP SOLAR is ok. I'm finding limitations when it comes to battery charging. I put on an Epever as is was inexpensive for a 40amp charger and gave me more control over charging. I'd love to have a Victron, but they're just a tad out of my price range just yet. Again thanks for all the inputs.

I was testing my inverter after a new install of a backup mppt charge controller and wanted to put it through its' paces. What I didn't count on is cloud edging that day. I am hoping the inverter, itself, wasn't just going crazy. I'm trying to figure out whether this is normal during cloud edging. Everything seemed to run fine. Just looking to see if I am correct in assuming that this is the norm. Thanks.

Hello. I'm trying to find out if there is anyone out there who has done a test regarding MPP SOLAR and their battery voltage metering on the State of Charge of a battery. There have been questions about this so I experimented (cheaply) to try to answer the question myself. This video is my evidence regarding that question that many seem to pose on youtube or in other blogs. Maybe I've just been lucky, but I don't see any discrepancies to the metering of their battery voltage.

I was doing a comparison of my rebranded MPP SOLAR AC Inverter output to AC Grid/Utility output. In my area (Provincial Philippines), it really made a difference in clean power. The Utility power can fluctuate up to 70 volts on a 230V 60Hz grid system. I was wondering if anyone else has this experience or is this normal...?

I am finally on the sixth month of this rebranded MPP SOLAR inverter and I have to say (knock on wood) so far so good. In fact, I've been quite impressed by its' ability to take direct sunlight and immediately change it into AC Power. In this video that's exactly what you'll see. If it used the battery, at all, it was minimal. I used a 360-370 watt power grinder on and off for about 15 to 20 minutes (most of which I just ran it for extended periods of time). I was testing two things....the over voltage (if it came on every time....it didn't) and how much battery was used. Surprisingly, with only 600W of panels in series and a lot of sun, the battery was already at float when I was finished using the grinder. This little unit was my first start at "testing" and "studying" what best way t use solar. Impressed so far...hopefully I don't jinks myself. Anyway...here is the video.

I am experimenting and testing an off brand MPP SOLAR Hybrid Inverter. It runs quite well so far and I have done some things to prevent issues that others have had. It's been four months and so far it's worked without a hitch. Being hybrid it will use the sun during the day directly and supplement battery when you need more, but at night it automatically goes into battery mode. You can get them as a hybrid that can grid tie, but the return was minimal as there is a cap to the money you can make from the power companies where I live. My hybrid only uses the grid as back up for charging in case there's little or no sun, but the grid here goes down quite often and my solar acts as the back up. Here are two links to help understand how I maintain my batteries and how I've setup the unit.

Hello Analytical, I'm new to the Forum. This is my first reply to anyone. I, too, am fairly new, but I have gathered a lot of information on YouTube from many different people. What I have found is interesting to say the least. To answer whether your unit will handle beyond 3kw...well, that's not something I would try, however I did view a video on YouTube where a guy in Africa put 3 times the rated power of his inverter through it because he set it to Utility only. That said, I'm not sure that's a good idea, but apparently it's been working for him. If that's true then my test unit, a little 2400W hybrid inverter should be okay. My unit, like yours, was probably made by MPP SOLAR. And yes, there have been a lot of differing views on it. Personally I think some guys are maxing the units beyond what they were made to do. My test unit is exactly that, but I only test to the limits and not over. For instance you mentioned more amps than watts...Though it is necessary to run higher amperage at times, I would try to avoid higher amperage. I set my PV array with higher amps in mind, at first, to help charge the batteries faster. I reconfigured it into serial to keep amperage down for two reasons, to keep the heat from the amps at lower temperatures and to keep from excess amperage when the "cloud effect" occurs. Still, higher voltages can also incur problems in the system, but it's less likely to burn anything down due to heat. Here is a video of two loads running. I have a video with three, but it went into over voltage and switched to grid use once about 55 amps were reached. What I will say is MPP SOLAR (Axpert or Infini) should not be used beyond their specifications and one should really read the manual carefully. There are some not so easy to understand points where maybe a translator (Chinese to English) did not work well. A guy who's had experience for four years recently posted/asked how to set up [1] to either SOL, SBU or UTI. Two guys on there thought SOL meant just using SOL was the most efficient way to run the machine. I guess it depends on what efficiency means to each user, but if they mean the "least amount of utility used", that would mean to use SBU (Priority is Solar, then the Battery and finally Utility). So yes, even older users can be fooled by the wording or translation. Here is a video that goes through a little bit of the Menu setup adjusting the [1] and [16] selections. I hope it helps you see some of what you'd expect from those units....though I think your Infini is a bit more advanced than this one. It may be a Hybrid, but I think that France's Imeon is a bit more robust...as they have a really top end warranty. This is where MPP SOLAR and all it's clones have some "maturing" to do, but for the price...it's still hard to beat especially if you're just learning. Much cheaper to blow one of these units up than an Imeon, an SMA, a Kaco, etc. SolaX, Goodwe and Growatt are also Hybrid, but are Chinese. That said these are top quality Chinese brands at higher prices. What I am finding, though, is that MPP SOLAR is now also making units for Growatt, Giant and Voltronic. All of them exactly like that of Axpert, Infini and others. The regional certifications probably change a bit of their circuitry to pass in different countries, but the unit and its' operation are the same. Your unit might have parallel capabilities. This might solve issues of going over while still using a set amount of PV. If you have three units, you can actually build a three phase system and just connect it to a junction box where you can separate them into three phase and single phase "areas". Three Inverters in parallel with a 4000W PV array will still give you more, per day, than your 15kW a day use. I believe the unit you're talking about has some grid tie capabilities. Mine doesn't give back to the Utility company, but I can supplement my system with it. But at 4000W worth of PV that gives you 4000x.8x5.5=17600W = 17.6kW a day. (0.8 is average because there's inefficiency and 5.5 is an average total "perfect" sunlight ~ not knowing how much actual sun you have). Anyway, I aimed slightly higher for your system though you only need 15kW a day. I've written a lot too now. I hope it helps and, at least, answered some questions. In the end, I personally think the MPP SOLAR's and their clones are fine if you don't try to kill them. If you want the best...then SMA...period, but once in a while they will also fail. Still, there are two guys I know with SMA's and MPP SOLAR (Infini). They love their MPP SOLAR and they know their SMA's will work. I know Outback is coming out with their Hybrid and many others are following suit. That says "something" about hybrid units that MPP SOLAR have made popular. It's making a sweep of the market structure for sure. I think they've solved a lot of issues through software. My test unit is only three months old and before I started videos, I did a lot of tweaking. The battery was the hardest part, but I later found out that people were draining my water tower so the battery kept coming on (at night) and drained the battery along with the water. Hahahaha....that problem has been resolved. Anyway good luck. Hope it helped either way. Peace..
