Growatt SPF5000ES Offgrid 9kw DIY Solar Project
lom replied to Pink7's topic in Alternative/Renewable Energy Forum
3.35V (53.6V) is 100% SOC (at least on my batteries) they are currently at 53.1V or 97% SOC but I have also seen them at 55.2V. I'm using Seplos BMS's which are set for a max charging voltage of 57.6V which the BMS has told my Deye inverter to provide. Maybe you need to raise the charging voltage? Anyway, don't charge or discharge when balancing, it takes forever to get balance if the there is additional current flowing through the cells when balancing. Your JK BMS has a good balancer compared to the ones (passive, low current) in my Seplos BMS's. -

Most important is to not balance while charging. A balancers algorithm is based on measuring cell voltages which must be quite stable or the algorithm fails. Cell voltages are not stable enough during charging, they vary a lot. -
Are there any cyber cafés in Koh Samui and Koh Phangan
lom replied to altayvan's topic in Koh Samui, Koh Phangan, Koh Tao
I can fax you a list of them. -
Make up your mind, you said in a previous post that RCDs or RCBOs works just fine with multiple earth or no earth at all.. ???? It is fine to have double protection but then make sure that the earth wire is not just a flimsy convenience earth wire for tripping an RCBO, it should be a real Protective Earth (PE) wire for which there are requirements not relying on an RCBO being present.

Sofar On-Grid Inverter firmware updates. Any luck?
lom replied to MJCM's topic in Alternative/Renewable Energy Forum
I'd go for 2x1.0mm² because the voltage from the CT is quite low and the cable is long, even a few mV of drop will give the inverter a flawed export result. -
Right, but if earth was connected to that equipment then the RCBO would have tripped without a person touching it. That's basically all you gain by having an earthed system when you are already protected by an RCBO, the earth cable can in this case be small since it only has to handle 30mA.

That's the right way to do it.

A handyman who wants to charge 2000 baht for a "survey fee"
lom replied to Nickcage49's topic in DIY Forum
It is his chance of getting a job by bidding for it, if he didn't then he would not have any customer. I've never charged a potential customer for a quotation and find it unbelievable that so many posters here finds it acceptable to do so. -
Korn left politics more than a month ago, he is no longer the leader of Chart Pattana Kla.

DIY Solar - some lessons learned for future expansion
lom replied to 4myr's topic in Alternative/Renewable Energy Forum
PEA is not the big problem, it is EGAT that doesn't want competition. -
I do not have Twitter, Instagram, or Facebook so instead I walkabout the streets shouting to randomly selected people what I've eaten, drunk, and what my home looks like. It is after all important to build networks. So far I have 3 followers, one is apparently a doctor and the others are policemen.

Water rationing starts 1st July
lom replied to Tropicalevo's topic in Koh Samui, Koh Phangan, Koh Tao
and those reservoirs are fed from Ratchaprapha. The Samui feed is just a continuation of of a water feed for the whole Suratthani, Nakorn Sri Tammarat area. You can say that the water comes from Donsak if you want.. That is also correct. -

Of course it is stored in reservoirs first, the water flow from the mainland would be severely restricted if it had to be pumped around the island by the mainland pumps. Another reason is obvious from the meaning of word reservoir. -

Power off island wide midnight to 4am?

It doesn't look like it is island-wide on the map in your other thread.
