MicroCare Off-grid Installation


Recommended Posts

Hi Everybody

In 2019 we've decided to go completely off-grid. This realized on 23 Dec 2019 after months of preparation (You will understand if you look at the photos below). 

In short, I had an outbuilding that was already at roof height and I've decided to do the installation in one of the rooms. It was possible to have all cabling inside of the wall.

I hope your site security is very good, because the ground mount is not elevated and is easy to access. What size is that Microcare Inverter

Site security is good. Temporary setup. Cannot decide whether I want to play with sun tracking or build an afdak. 

10kW inverter

4x4 guys are another species. They live in 12V land, they think National Luna makes the greatest stuff, and it's amazing how much stuff they'll put onto a single 100W module... at least until day two 🙂

 

You can say that again @plonkster . Me and TTT are fighting for our lifes there. Hahahahahaha. We had a guy "wit warm" yesterday, i think he started beading his keyboard. 

Oooooooo yes, and don't forget ther 105ah camping batteries. 😁

@LouisT seen it yesterday.  Hahahahaah

I am not a member on any of the 4x4 forums, but I remember stumbling onto a thread one day on some SA 4x4 forum, and the one guy had the perfect idea for a perpetual motion machine, other members tried to explain to him that it wasn't possible, to him the law of thermodynamics was just a annoying law soon to be legislated away :P 

IIRC he also drove a Land Rover, make with that what you will :P.

It will take years for them to understand what a deep cycle battery mean

Yes understood but its for a LiFePO4 battery correct

Correct LiFePO4. I assume you have the manual. Below my settings:

 

8.1) Float Voltage = 13.4V (X4) 

8.2) Boost Voltage = 13.6V (X4) 

8.3) Boost to Float Voltage interval = 1 hour

8.4) Boost to Float Current = 15A

8.5) Equalise Charge Mode = Manual

8.6) Battery set Voltage = Auto

8.7) Charge limit = 80%

8.9) Set operation Mode = fmode0

Thanks for sending this.

I do have the MPPT manual but there is no specific settings for different chemistry batteries.

For interest sake how long does it take for your batteries to go to charge ?

I should have been clear that I don't have a solarmd battery but other LiFePO4

My pleasure 

1) The settings should come from your battery supplier. The settings above is from SolarMD. 

2) Not too sure what you mean, but as soon as I have sunlight on my panels the MPPT's start charging. My batteries are charged by 11:30 to 12:30.

3) Understood👍
