MPP-Solar LVX-6048

I asked MPP again about updates for the Lvx6048
This is the reply

“There has never been a firmware updated for LVX6048.”
 
MPPSolar is making me a little nervous-
My first lvx6048 at only 18 amps max and 360 voc on a good day developed some kind of internal PV short on a cloudy day ??? (no smoke, no smell nothing burnt)
I am sending it back to SANTAN solar to be fixed because it is still under warranty. My second one I bought from watts247 because they had them in stock and when I opened the box , all the screw heads on the left side had been snapped off. I hooked up the unit and it is working fine, but sheese louise,
Cant their QC do a bit better job?
 
I would also love the firmware update, please. Just joined the forum. I have 4 of the lvx6048s on order and am a little worried about how to get the latest firmware after reading through the posts. I think this looks a very good source of knowledge and suggestion.
That idle consumption will be crazy. Around 13kwh per day.

Hi, the file is in my last post, l have my system in Input voltage range on APL, before I had it on UPS and I had a lot off problem after switching to APL my system is working with no problem. Do any one had the same problem. Good day.

I see you had posted the LVX6048 you own has 135W of idle draw. However if the unit is powering anything, then it is a moot point as this would fall under inverter efficiency.

Having said that, with 4 units, it would be wasteful if 2 of the units were just idling along.

It's not a moot point if your typical loads are low power or infrequently run

If you don't mind pushing the on / off button you can charge your 48V batteries even if the inverter is in off mode. So it doesn't use the 140 Watts standby power. Then if you need the extra ac power you can turn the inverter on.

I do that with my truck camper, I mounted a remote switch right in the galley so you just reach across and turn it on/off.
 
I know this thread is not about the LVX6048WP and that it is not released yet but do we think the idle power consumption would be similar or lower based on the type of inverter?

Unfortunately I think it'll be the same

Low frequency inverters have a high idle draw compared to high frequency inverters.
 
The LV6548 is listed, but not for grid-tie. According to MPP Solar, the new LVX6048WP will be listed for Grid -tie. Its also a low frequency inverter, and water proof( no fans like SMA)
I have just been confirmed from MPP Solar Taiwan that LVX6048WP is a HIGH FREQUENCY Inverter.
 
Why is it so heavy then?
Like so many items in the solar industry, naming conventions are in the eye of the supplier...

Common logic:

Heavy with a big fat transformer = Low Frequency
Light with tiny or no transformer = High Frequency
 
I have just been confirmed from MPP Solar Taiwan that LVX6048WP is a HIGH FREQUENCY Inverter.
According to their US supplier, its low frequency. I have not yet opened the boxes, so I have not checked myself yet. I do know they are MUCH heavier than my LV6548's.
From Watts247.com website:

LVX6048WP​

$2,200.00


It is the waterproof version of the upgraded LVX6048 (more solar input capacity too!), Grid feedback, battery optional, dual mppts, Low Frequency, split phase ……. stackable you name it, wifi..
 
Just because it has a transformer doesn't necessarily makes it high/low frequency. It could use the transformer to generate the neutral but still have the high frequency design.

Agreed. In fact the over voltage time in the manual is in the ms range, which is clearly a mosfet type range. A low frequency inverter should be in the seconds range.

Maximum Output Fault Current/Duration
90 A per phase / 1ms.
My SMA inverters can handle very high amps for 4 seconds.
If this is correct, then Watt247.com did false advertising, and I will be sending them back.
 
Ehh I’m not sure I would call it false advertising. That usually implies malicious intent, I think in this case they were just ignorant.

In general people just assume transformer = low frequency. But I think MPP took a high frequency grid tied 230v inverter slapped a transformer on top to get 240/120 split phase. I can't confirm if this is the case or not since I'm not all that interested in this inverter but just a hunch.
