Rambling about software updates slowly making this Megarevo R8KLNA inverter useful.

That's a good sign they are improving things. Not having export here I'm dumping my extra solar into the A/C.

Long time coming. I'm afraid they've lost a lot of their steam pushing the product so early. I do think the hardware is good but as Mr. Prouse says the software is what kills these inverters on usability. And documentation. Documentation is hard, especially across language barriers!

I will put in a good word for Megarevo. They really helped me out today putting me in contact with Portugal office to source a wifi logger (4 pin). The manual was hard as it's really basic but i worked it out in a few hours. Worst thing i did after hanging it was forget the PV breaker was off. 😂

Ha ha I left the RSD button in when I first set mine up and couldn't figure out why it wasn't working! Glad you had a great experience!

I was wondering if you ever had any issues with your powmr charge controllers when a cloud passes over? About once a day a cloud can pass over and my 100 powmr will do this thing where the fans start ramping up and down erratically. Only way to get it to do right is completely disconnect solar and battery then hook it back up and it works. the rest the day with no issues. My other powmr is a 3000 watt all in one and the charge controller on it will be working correctly then q cloud passes over and it will suddenly barely be charging and be stuck like that till i completely unhook it and then hook it all back up. So yeah i was wondering if ypu ever had those kinda problems with yours? Seems if i over panel them at all then it makes the problem much worse. I just ordered a 150-70 victron so hopefully it will work right for me. And bro i lile your videos. You have taught me alot and helped me with confidence in building my system

I have 2 Megarevo inverters. I have it split into two separate systems 14 Trina panels 550 about 480v on each inverter working good feeding 60 to 80kw a day. Would like to get your input on my system. Ernie

Mr Beene are there any setting changes to make on a Megarevo to stop charging halt when one battery reaches 100%? I have 3 UFO 48v 200ah batteries. They are close but over a few weeks drift out by 13% or so. I have flipped the breaker on the most charged battery at 99% and this works but is there a setting on the inverter to prevent the stop charge?

You using closed loop communication and doc for charging? Or voltage?

@@BeeneEnergy connected to the address 1 battery with CAN connection. Charge voltage 54v I think auto set. All batteries rs485 connected to each other. In charge mode 6KL1 shows charge on most charged battery and on discharge (say at night) shows most depleted battery.

@@BeeneEnergy hi mate My packs are only 15 cells 3.2V nominal. They rest after full charge no loads at around 3380mV. Would this Lead Acid setting be OK for 90-95% SOC?

Do you know the connection diagram of megarevo with solar assistant?, thanks

@BeeneEnergy 3 ай бұрын

Iirc it’s pins 2 and 3 of the monitoring connector over to an rs485 adapter.

Thx for the info...This should've been a go to inverter but they messed up so bad Will P couldn't even get it to work...who's going to trust it now? I wanted one, but no way will I touch it!

Yep, going to be hard to get trust back.

My 6KL1 off grid has been totally solid for 12 days. I'm a total novice. No issues. To go on grid the manual is too basic imo. No issues with CAN port to Li battery.

How are your Megarevos doing ?

@BeeneEnergy 8 ай бұрын

Fantastic! They continue to chug along. Had a $20 bill last month.

@cainweber1978 Жыл бұрын

I see you're using Solar Assistant. Did you make a video how you removed the 4 pin rs485 connection and build a 5v usb etc? Atm this is beyond my ability without a how to video.

@BeeneEnergy Жыл бұрын

No! I've been trying to find the 4 pin connector so I can make a megarevo to solar assistant adapter but haven't found it yet. Just using some wire stuck up in the pins for right now. Very janky.

@@BeeneEnergy other thing I was going to try were red ferrules and crimp to the rs485 pins. Shame they used such a wierd connection. Solis make these wifi connections but apparently dont work with Megarevo.
