Hi there - first time posting in the forum, and fairly new to solar, though I have a technical background.

I am in Canada, looking for an all-in-one inverter/charger. Does anyone have any experience with the 6500EX-48 model from The Solar Power Store (branded “Maple Leaf”)?

Search LV6548 by MPP solar, then check out voltronic... The maple leaf isn't an eg4 clone.
The 6548 is a solid inverter. The 250 max voc model, in particular, seem to be the most reliable
I've seen some bad posts about that vendor, Search on here...
Good luck.

Edited for clarity.
Also I believe SGP ships to Canada for free and they have a Voltronic clone as well.

I disagree with this portion at least with regards to the MPPT and its ratings.


18A PV input current limit + 250Voc limit means you're not going to get anywhere near the claimed 4000W output.

4000W/18A = 222Vmp

there aren't panels on the planet that will generate a Vmp of 222V that won't blow 250Voc @ 25°C.

The most you can hope for is about 3200W/MPPT.

This is true, the MPPT ratings were kind of garbage. But I think he was inferring the reliability of the inverter. The MPP Solar 250v model had FAR FAR less problems than any of the other brands.

My comments were only on the MPPTs. I don't recall this model ever presenting any issues beyond those by frustrated members not getting the 4000W/MPPT from 4kW+ arrays.

I remember those, I personally only had 3500w connected, but it was clipping pretty bad

I have one on the way and will let you know.. Looks to be a rebranded LV6548... despite the 6500EX-48 name. I only have 4kW of panels so will have dual 2kW strings and the unit seemed to be well suited to that.

Was also looking at the SP6548 with the 390V PVOC but not sure if the consumption on the higher V units has been optimized yet.
 
I expect this is a re-branded Voltronic.
My concern with the 6548 - 390v models is the higher standby current Lithium Solar illustrated.
The 6548 -250v models appear to have been solid performers, at least from what I have seen posted here on the forum over the last couple of years.
Hope your unit works like the MPP version, hope to see you post follow up once you have it up and running for a while @Detritalgeo
 
finally got around to opening it up...

some thoughts so far... its just a LV6548 but cheaper than the MPP. It is not the same as the EG4 6500EX-48 model.

I just saw SPS just listed a 500VOC PV max model of this and the lower PV model I have is sold out.

I see, they are still the same core inverter, EG4 made the 'upgrades' you mentioned and MPP has a 360voc version now.
Be glad you got the 250VOC version, they are the most reliable / trouble free....

And the 390v PV DC version had reportedly much higher idle consumption...
over 100w idle per @LithiumSolar youtube vid.
I am not so sure these are 'cheaper' - for MPP stuff check out Maximum-solar.online
the 6548 - 390vDC - is listed at $959.00 USD
 
I agree... I have panels that wont allow to get the 4kW PV input unless I want clipping... 405W Longi 405M's with ~40VOC and 13A at max... I have them in 5S right now until I see how much the voltage spikes in the coldest days..

With ya on that one @Lt.Dan !
I thought my 6048's were 'high idle' at 75W - now I feel these are 'not that bad' but will trade up to something better in a year or two, I would like higher PV DC voltage - 250 would be fine, and maybe 50W idle would suit me.

I looked up this Longi 405, it has VOC of 37 and a temperature delta of -0.265 (quite low compared to most)
In 5s your base VOC will be 5 x 37 = 185 (at 25C)
the delta at -0.265 would mean to reach 250v it would need to be: 250-185 = 65 meaning you would be okay anywhere on earth and remain above the 250v threashold.
-0.265 x (-50) = 13v for the temperature delta. 185 + 13 = 198 ie nothing to worry about.

On Vancouver Island it would only rarely get to -15c for a few days.. I could run 6S in the summer but the winter may be tight so I am sticking with 5S.
 
My current issues with these units (I have not been able to get any response from the retailer over the past month either by phone, email or web form)

1. One unit loses settings after reset
* Have to change it back from single to 2P1 each time
* is there a way to reset the unit from a fault state without cuttings solar and grid power to it?
2. Unit faults with F80, power gets cut
* unclear if this happens only when solar is connected to 2P1 unit
3. F52 error, power gets cut
* This has happened multiple times when moving from SUB to SBU, I'm not sure that's the only time it happens
4. Long switching time > specifications
* when switching to battery there is a long enough delay to see the power drop and come back which causes some devices to lose their settings, and I expect is not particularly healthy for anything hooked up
5. Unexplained switch to bypass vs battery
* some times (usually at about half load [3-4kW]) the units will switch to what appears to be bypass but still feeding power from the batteries
* when in this state it does not report the current draw from the batteries
