low output from charge controller

So you went from 26 cents per Kwh to $1 per kwh. You call that saving money?

for me it was about 30c per kwh after network fees. for me its not about saving money, its poor service, NO service. truck took out my power cable from pole to house across the main rd, ripped off the gable and smashed my fence, lucky no one killed. ausgrid never reconnected it , they told me its my expense to get the repairs. my immediate concern was getting power and thanks for your help i have done that. lawyers can wait.

re is very popular in australia, except for bala he hates it. families here get $1500 quarterly power bills so with the solar panel rebates the government has offered in recent years the take up for roof top grid tie solar panels has been huge. they now account for over a gigawatt of power generation. the breakdown of a power bill in NSW is about 80c a day for network fees, then average about 26c per kwh. since i dont use much power i will stay off grid. finding some good heavy duty 12v batteries lately on the kerb, some of them are taking a charge well so still have life. will set up a junked battery bank soon.

Not everyone is fortunate enough to have a local RE/PV store, so you can understand our misunderstanding.

the local store has inverters and CCs so they should have dc fuses

Try MARINE shops.

[inetdog]

no, but fire has been on my mind, shall ask at the local store for appropriate fuse

The local store may not be in a position to advise you on a DC capable fuse. Blue Sea is one manufacturer of good DC fuses and holders for high current applications, but there are others. Automotive fuse holders and fuses may not do the job, especially at voltages above 12V DC.

Do you have the DC wiring from battery to inverter fused accordingly?

maximum i load on these is 75amps when using an 1800w chainsaw

200 amp gator clips are a marketing fiction. Except for one time short usage like jump starting.

Even if the clamps can handle the current, the interface to the battery posts cannot.

thanks, iv used ring lug terminals with bolts where i can. the gator clips are on the CC cables and .. yes .. a 2000w inverter. they are 200amp gator clips on the inverter and the reason i use gator clips is because of frequent reconfiguration, so they dont get left for long enough to suffer the effects of time and vibration. i always check these connections. already had some melted copper strands that came into contact with the battery post on the inside of a gator clip

Which brings up another important point:
At the current values common with CCs and especially with inverters, any kind of spring loaded clamp (at either the battery or the CC end) should NOT be used.
Spade or ring lug terminals and bolts or binding posts are the way to go.
Any spring clamp will not provide a consistent low resistance in the face of time and vibration. And when it starts to heat up you will have real problems, not just poor battery charging.

Reminds me of a 60/70's band.

yes these gator clamps have an extended bracket for anchoring the cable over the insulated part of the wire

Glad to hear that you found it.
If you used the proper connector and proper crimp tools (not just mashing with pliers) the connection should have been as good in terms of resistance as a soldered connection and would have better mechanical properties.
One problem with soldering, especially with stranded wire, is that you get a stress concentration that will eventually break the wire unless you have strain relief beyond the point where the wire is coated with solder.
