Thank you very much for looking over that and confirming. I shall get on with this now!

I need to wire in a thermostat between the battery and a heater. Iv got a diagram that is supplied with the thermostat. It shows the cables splitting here there and everywhere. I have attached my own technical drawing, would this work to the same degree as the supplied diagram? I would just...

Okay would it be sensible to run my batteries at 24v with 4mm cable no fuse?

Wing it and hope for the best then ?

manual stated specs

Rather than start a new thread, I thought maybe wise to add this here... Could anyone shed any light onto why it states in my 400 watt turbine manual that I need 10mm wire for a 12v system and 2.5mm wire for a 48v system, all seems backwards or am I the backwards one?! Iv ordered a load of 4mm...

Thank you, divided not times ?

Yeah I know the sparks, just the same as hooking up a car battery. Id need to connect the battery to the mppt first so wouldn't be anything coming from the controller just the juice in the battery. I may give it a miss as I cant see a huge point in it once iv isolated the source of power. Just...

Looking at the inside of that im not sure how that would even stop an arc of 60+ amps?! A thought came to mind, I should always isolate my panels before my batteries to save damage to the mppt. So by bearing that im mind and wanting to stop power from my mppt to the batteries, step one.. turn...

Of course as soon as I post that message I find something ? Its from voltracon energy but I see no reviews

Could I please as for a recommendation on an isolator around 80 amps from my mppt to my batteries. Iv managed to find a 32a isolator for solar to mppt at £25-30 which I'm happy with, however my search results for an 80amp are all in the area of £150-200 , am I looking in the wrong place? ?

I will check if the hybrid inverter is internally fused. The turbine isn't anything special, just an eco-worthy model I was given. I dont think I could trust it without some protection, the emphasis on protecting your system from fire with solar is huge. Wind turbines it seems not ?

Yes of course, I would fuse/protect it against its max output at 400 watt. Is that common practice with these turbines then to save interfering with the brake function? Really not getting a whole lot of information from Google, it seems the most don't bother with any protection this side of...

Thank you, thats now on its way. Hopefully get this show on the road in the coming week.

if its of any use, here is the spec sheet...

I have a 400 watt wind turbine, I will be lucky if it produces anywhere near that but I'm putting it up anyway as it might do something! My question would be to fuse or not to fuse? The charge controller has a brake function, so if I was to fuse between turbine and controller and say I blow a...

The 16mm cable is rated at 110amp I won't loose any power with cable this size would I? I know I need to keep my cables as short as possible to reduce voltage drop so im thinking that might apply to to cable diameter, more copper than required ?

Okay I get the message fuse everything! ? should I need to worry about fusing my neutral cables? Looks like today is fuse shopping day

ok so im hearing i should leave the breakers alone. So as far as I get it with some questionable points, the setup should look a little something like this... Panel - fuse 20a - isolator 20-30a - mppt - fuse 80-100a - isolator? - battery - fuse unknown amps - future inverter - fuse? - load...

I have been looking at those inline fuses, nice and simple for dealing with the panel to mppt. If I'm hardly switching it off then I may aswell use the breaker ;) ?

These resting are just to get me through winter. I will load up with the garden water feature and possibly the garden room. Fans will also be running alot more during the summer and they are switchable meaning I can turn them up a setting, more juice more blowy! Or I might just boil a kettle...

I'm all DC loads pulling a max of 50 watts at any given time, all low power water pumps, light and element. My loads will all be individually switched so I can shut them off with ease. My biggest current would be from the mppt to batteries at 60amp I believe. Solar panels at around 11amp I...

Could I ask what you would recommend as a switch/isolation method in the case of me wanting to perform maintenance etc. Presumably a straight forward isolator switch would suffer with the same arcing difficulties that breakers do?

If I'm following you right, a common fault with these breakers is the polarity heading the wrong direction causing the arc to almost intense. As far as the description goes these breakers can flow both directions and are also suitable for manual switching as iv read this can also be an issue.

I understand it is harder to stop an arc with DC as apposed to AC, the latest breakers Renogy sell also use magnets inside the breaker to extinguish the arc. I would have hoped that Renogy wouldn't be selling counterfeits, has this been known with them in the past? I will do some googling to...

Am I okay with a 63amp breaker between the mppt and batteries? I keep reading bad reviews about these ebay cheap breakers which has put me off. Renogy have dc breakers but their biggest is 63amp and I know you mentioned a 100amp fuse between the two.

I think I'm definitely going to ground via means of an earth rod to be on the safe side

Yes I see the mixed opinions when it comes to grounding, might just do it for the safety aspect. Would you recommend me sending the load cable from the mppt through a breaker before it hits the load? I'm just thinking along the lines of the controller breaking...

Perfect , looks like we are in business! Just need to work out the grounding cable size from the panels, any ideas on this front?

Brilliant, if a fuse will do the job I shal order one of them. Presumably just the one on the live. Toolstation have some clearance breakers, so I will grab one of them. Will see if they have a 100 amp going cheap as I guess it could be handy to shut the panels off from the controller

Id I remember right the epever manual recommends 16mm cable, I think you also send me a link along those lines too

Having a good read of the somewhat vague manuals and data sheets for the solar panels, I need to look at grounding and a circuit breaker before the mppt and possibly after should the charge controller fail? I know from the charge controller I will have 60 amps to break. From the panels to...

Right, thank you all very much! I now understand how this works, explained in many different ways which has made life easier for this idiot. So I can take from this, the solar panel isn't going to explode! ? ? ?

The battery isn't producing energy every second its exposed to light thought?

Ok so this controller would leave me okay with a battery upgrade, thats great to know. Thank you
