Maple Leaf Branded 6500EX-48 - Any Experince?

BJB. · Jun 29, 2023

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.

Funny how EG4 has grown so large, that any 6500w AIO is now being thought of as an EG4 clone rather than the actual manufacture lol.

The 6548 is a solid inverter, 250v mppt version in particular.

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

https://watts247.com/manuals/mpp/LV6548.pdf

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.

Correct. I'll edit the post.
Thanks @sunshine_eggo for the additional explanation.

sunshine_eggo · Jun 29, 2023

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

Everybody seemed to miss the 18A PV input limit. That's what's really crippling. Few 250Voc MPPT are that crippling.

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.

OffGridForGood · Oct 9, 2023

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

Detritalgeo · Oct 11, 2023

The unit arrived today.. Will be some time before I get it mounted up.

Detritalgeo · Nov 23, 2023

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.

Detritalgeo · Nov 23, 2023

This one is only 250VOC.. Not 500VOC like on the EG4. It also does not have PV input strain relief like EG4's 6500EX, it has MC4 adapters.

42OhmsPA · Nov 23, 2023

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

Lt.Dan · Nov 23, 2023

250v VOC limit is fine IMO. I ran a 6s array at 300ft away at 37.6VOC each for a couple years and it worked great. The need for 500VOC is not needed if it comes with the extra 60w of idle consumption that the EG4 comes with

Detritalgeo · Nov 23, 2023

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..
