QUOTE(nikrizal @ Jun 23 2024, 05:43 PM) Hehehe unlikely I’ll do it. But there was a study about this, however the addition of aluminium foil will only increase 1% of solar energy, not worth it can forget about it, lolStudy on aluminium foil effect to solar energy production |

is it normal that String inverter is powered by Solar DC and not TNB AC?
then inverter will on and off following the supply from Solar. |

QUOTE(cdspins @ Jun 26 2024, 10:50 AM) Sorry don't really get your question. My understanding is that the inverter sole purpose is to convert DC power from solar to AC. So ya, TNB power is not use at all. Maybe as a standby power for the power switch or data logger. yes, u get my question correctly,And yes, inverter will on and off, happens in the morning when the sun is just not bright enough, sometimes will on and off a few times before it is on fully, based on my observation. so the inverter will on and off daily, will this reduce the inverter life span? and is it normal to be installed this way? |

QUOTE(Avangelice @ Jul 1 2024, 10:23 AM) 11kwp solar panel capacity 9.33 years to ROI. Inverter 12kw hybrid, got monitoring apps LifePO4 battery 15kwh DC earthing Manual change over single phase Testing & Commissioning Total RM56,000 Got a quotation from a company in kuching. Monthly sesco bill myr 500 and on single phase. By investing in this system, you will acquire savings on 99% of your monthly electricity bills. It's a tad too expensive compare to what u guys are paying not worth, and sarawak using hydro power, even more green ba. so no point. |

QUOTE(cdspins @ Jul 1 2024, 10:37 AM) Drop the battery, I think it will reduce the price by quite alot, do not need battery currently, further down the road when battery becomes cheap then only consider. By the way, sesco bill RM500 is about how many kwh? QUOTE(ayamxxx @ Jul 1 2024, 10:38 AM) this without NEM, i don't think he can drop the battery |

QUOTE(ayamxxx @ Jul 1 2024, 10:41 AM) I believe can as what others have been doing so far, use TNB as the "battery" provider, mean total generated by solar - current supply by TNB. Correct? he at sarawak. ayamxxx liked this post

QUOTE(cdspins @ Jul 8 2024, 11:26 AM) Abit confusing though, you receive the NEW welcome letter from TNB? isn't that means you can switch on?Anyway, it is just 3 July, TnB usually response in about 1 to 2 weeks, so there is still much waiting time. not yet.the solar installed complete on 21 jun. |
