I just noticed Brown spots on my one battery breakers front and under on the one pole. Any ideas what is this? Should i still use it? replace? It have never switched yet Pink

I used THB 300K. You can see some more details here Pink

my usage/production is 20-43kw per day and my 300k DIY setup is 2 x 5K inverters. 28 x 330w pannels and 30kw batteries. My electric bill used to be around 3000/month upto 4500/month, now its 38-1xx bt/month Pink

With so good deal its worth the wait! Pink

How many total watt solarpanel when all up? Pink

Great inverter. When you expect to get your battery deal delivered? Pink

Thats allot of solar capacity !!! You will built some kind of rack for it? Whats your plans for inverter for this? Pink

Until this month i been very confident on my solar power capacity, but with this heat, location of the sun (Im getting max 6000kwh now, 5-6 months ago 7000kwh was max) and school off so kids AC running in daytime also Im might a bit in the short side. Pink

That look to be a good deal on a good solution. Looks great!!! Pink

Yes it was panel to panel connections. Pink

Not easy to say but could be it happened around time we got some cleaning done with hose but I dont know whats the chance for any water to have made the issue. Im quite sure it was not matter of not plugged. Both connectors were original connectors on the solar panels so I would expect they to be well crimped..but I guess fails happens. Pink

Generated 31+kw/h today. Its long time since I was able to get this level in a day !!! Pink

Even I have solar i must admit that we still use gas for cooking. Most my life I used electric stoves but after get used to gas for cooking its not easy turn back to electric. I love how fast it is to fire up and ready to cook. Pink

I guess its what you mention last day: bad connection between the 2 panels. The 2 connectors was melted and no other damages to see. Pink

Yesterday afternoon I pulled down the one panel and replaced one connector on each on the two pannels and mounted it all back and connected the wires. This morning i first tested the voltage on the breaker before open it to power the inverter. Now i see power is same or better than the other side of the roof so the fix look to be successfully as for now. Pink

Now I feel it strange i not discovered it before, maybe if it was in front side roof i have seen it before. The good part of this is that I found the reason why I am on low power and it should be fixable. Pink

Yes I was thinking same. I will pull down the 2 affected panels and replace connectors and test them. Hopefully panels still ok. When close up photo i see black on the steel so look like some electrical shock pulled the connector apart and broke it. Pink

As mention in last post last weeks i was starting to get lower watt level than what im used to. First i thought it was the moment of the sun..then last day i was sure it was quite sure it was a matter of cleaning. But after cleaning still same. Than this morning we found out them my one side of panels have a broken connector so that side is 50% with only 7 of the 14 active. From photo look like the connector is damages and we see some black on the steel frame on the roof. Any idea how this could have happen? Now i make a plan to take down the one panel who block the access to the panel with issue then replace the connectors and test the panel with watt/amp meter. Pink

Build smart so you get a well insulated home who is easy and need low energy to keep cold. Also use inverter electronics for Ac ref etc. Pink

Consider a quality aircon with Inverter. I use to run my whole home at 1000 kw/h or so with 18k btu running + 2 large refrigateors/freezers ( with inverter) + 1-2 tc + 1 to 2 pc ++. Count in the high startup power needed but after that power usage is not high with a quality units. I use Mitsubishi Electric mr slim 18BTU Pink

So at this time in getting 4000 Watt level as max, the he time I installed my max level was 7000 watt. This time of the year my one roof side perform better because of the sun position and im just able to get needed power per day so I might after a years experience with all seasons should consider some more panels. I do plan a cleaning pf panels very soon but lets see how much that will improve. I noticed i produce about same in light cloudy weather as in full sunny weather. Pink

Nice Numbers. Happy New Year too. Pink

My vote goes to location B. I have do a DIY offgrid setup with 30kwh batteries and 9-10kw capacity for 300K. If you do 3 x inverters in parallel then x2 and for example 2 x 30kwh batteries that setup with a backup generator you should be good. Btw I saw in another tread prices on SPF5000ES very good in Thailand now, they great to parallel setup. Regards Pink

Yes I have one of those large oval black ones used when building so it will be fine for this. I was not sold as a set but i picked the items i wanted. I payed just over 1kthb delivered. Pink

After some searching I found an expandable aluminum window cleaning equipment on Lazada that I want to try. Max 4.5m the one i ordered. Pink
