Hi again... The best is to search for the thread on this site and also to read the AEVA thread. they are both very good ito instructions and things to watch out for... Regards Mark

Hi @Deonsr Here is the thread link - just make sure of your Axpert Model! Regards Mark

Been doing a bit of surfing the "http://forum.solar-electric.com/discussions" site and amazed at home many 24V system there are... I think this is almost the middle ground. Less batteries - higher ah @Chris Hobson but still the ability to run big loads for small periods. Most people also have a gennie to use when the welder needs to be used for example. Off grid you probably have one anyway. @Chris Hobson I would explore the 24V option for your situation. NOT 12V ( @TTT is about to step in )

Same concern but if you reverse the fans like I have then they blow upwards and so hot air wont pool in the breaker box...should be ok.... you could add a vent in the bottom ... Must say I like the box... very much... does it have a cover/door...? Sent from my SM-G800F using Tapatalk

Thanks @superdiy - that helps alot! A challenge that is not simple to sell to the "man with the clipboard".

Ok right... if AC out is plugged into main db in then yes...... assumed a dedicated subdb[emoji2] Sent from my SM-G800F using Tapatalk

It will be just like plugging in a UPS or a hairdryer... cannot feed back at all...
-
Its not pugged in... for the Genny so you can charge the battery bank!!
-
I would put a 3pin 16A plug on the AC input side. Leave it unplugged until needed at night
-
Get a small PC or tablet. Soon you will want to monitor multiple devices and this will allow for expansion!
-
If you are talking about AC input into the Axpert then YES> I do this with my small 1kva Axpert. I also have a multiplug on the AC output which I then use extension cord to loads when needed. Make sure the AC input amps doesn't overload the plug rating.

I would support this @Energy!

Do you have a wiring diagram for your fancy pants switch [emoji12] Sent from my SM-G800F using Tapatalk

@TTT But you are switching using a relay not directly the load?
-
Ha... TTT - I'm nervous... when the chaps put this in the manual...! Especially a high amps appliance = geyser...
-
My old board was a nightmare... the new DB now has a Samite rail (I replaced the DIN rail) at the top for the old mains and earth leakage plus the new samite surge protection and my old plug breakers (samite and reused). Next 2 layers now DIN with transfer switches and house. Out buildings (plus tenants) on the blue phase with own breaker (40A). I've loads of expansion options. Plus almost exactly the same size as the old DB board.

That was my thinking. I would rather have the relay on if something goes wrong so that freezer doesn't go off. The SOC is then monitored by software (SolWeb) to switch to Grid if needed. And my Low Voltage cutoff is also a third damage limitation option.
-
One day but I had some tough requirements... The sparky and I spent alot of time planning. 3 phases, each on a transfer switch means I can now run various outbuildings either on or off inverter. The house has 2 transfer switches: One for heavy loads (stove and geyser) on a phase, and one for the rest. Each phase is also colour coded on the board so I can monitor usage. We are on a farm so I plan to go off grid... (note the word plan/dream). Worth the money - any day. Also I now know whats happening on the board and also don't have floating neutral issues... added surge protection as apparently Eskom doesn't pay out if you don't have them. -
Are you using the Axpert relay or BMV . I am using the BMV to drive a 12V circuit which switches a seperate 10A 220V relay. Scared of using the BMV direct given the 60V limit
-
Hi All Just wanting to get an idea of your views on the NO vs NC to control an appliance (old freezer) via relay connected to the BMV 700/2. I have the relay (AC: 220V 10A; DC: 12V) currently wired as NO to the BMV (Default Relay / NOT Inverted) and so when SOC is above X the relay is not energised (STAYS CLOSED) and when SOC is below X it is energised and then OPENS. What are your thoughts: OPEN by default (NO), or CLOSED by default (NC)

@plonkster I ended up removing and stripping the whole DB and then replacing with a surface mount over the hole. 3 phase so Hager transfer switch on each phase as well as subdb for extra lights and plugs from inverter. Before: A "farm" mess... After:
