Re: Solar Power

We have a 7.5 kw gen with ATS. All critical electronics and lights are on UPS boxes. Blackout happens, we often aren't aware until we hear the generator running. Brownouts can be a pain, sometimes. The ATS won't switch over unless a threshold (dunno specifics) is crossed. Our area has gotten quite ...

Re: Solar Power

I am quite happy with my generator to cover blackouts. I canmot see how any of you will ever get to a breakeven point? In this thread we have gone over the financials many times. With grid-tie, and the ability to just feed the grid and take back what you put in, you can get a pay back within ten ye...

Re: Solar Power

With the crazy high prices here why bother? how many years to even break even?? I think never. what with falures and battery replacement etc etc, it clearly is not encouraged here with the electric monopoly. With grid-tie you don't need batteries. If you DIY purchase and install a grid-tie system, ...

Re: Solar Power

all the bureaucrats have to have their chance to stamp the paperwork! "Bureaucrats"? Where might they be? When I tried getting into the roof-top incentive program, all I encountered were PEA people. Had to hire a PEA engineer to help do the paperwork on "their" system layout. Had to go sit in a mee...

Re: Solar Power

The wife has tried to contact the shop owner a few times, via @line and by phone, but he hasn't gotten back to her. In any case, I am not really in that much of a rush to buy one. I just hate that the price of solar panels hasn't budged much in Thailand over the last few years. I just emailed a req...

Re: Solar Power

Crikey, I’m going through these posts and and to be honest I’m a bit mind blown, I’m just building a place and I’d really like to use solar power so this is a big ask because I’m sure there are a million combinations, but, what I’d like is a complete starter package suggestion that goes from panels...

Re: Solar Power

I have Kolsat AGM 200ah and they seem much more stable than the flooded Volta 160 I had before. Kolsat were 11.300B. I could not find the spec on these Kolsat so I used a Victron spec for AGM https://www.victronenergy.com/upload/documents/Datasheet-GEL-and-AGM-Batteries-EN.pdf Kolsat AGM 200ah vs V...

Re: Solar Power

Hmmm, that page says those 3K batts are only 4,200 THB per battery. So, you paid 2,000 THB more for tax and delivery?

Re: Solar Power

When it comes to these deep-cycle batteries, more mass is better. On a Kg/Wh basis those batteries are 0.0215 Kg/Wh vs the Volta VIN150 at 0.0294 Kg/Wh with the Volta you'd get 38% more lead for about the same cost per Wh (or less). The 3K batts don't give the "dry weight" spec so a little difficult...

Re: Solar Power

JR: I have no personal experience with AGM batteries for solar, so I could always have it wrong... but, a few websites that profess to be experts in batteries (as the link below) state it like this... "As with all gelled and sealed units, AGM batteries are sensitive to overcharging. " http://battery...

Are you still AC coupling your grid-tie inverters to back-feed into your batteries? No problems with that?

Re: Solar Power

After all this time, do you have any recommendations for deep cycle batteries? Well, I'm not sure that my opinion on deep-cycle batteries is of much use. During most of the year I run the grid-tie inverter(s) because I don't have enough power (2,700W) to even meet my daytime use as A/C and fans are...
