even on same capacity, solar generation can be affected by area you live, direction & angle of your roof..Home solar 4 months in.

QUOTE(sgpdsmss @ Jan 8 2025, 06:24 PM) *cut* BTW.. did u switch on solar power breaker to use the solar power ? or just off n wait for tnb? actually ...my also installed 3RdJan .. solar admin told my meter need to change ..wait for tnb ppl call for booking time date for change meter .. until today ..still no call ... thanks .... 1. Go to MyTNB website, under Application , send a Ticket to ask why the delays. 2. Make sure you don't missed call or ignore calls from strangers. I was ignoring strangers' calls (using Truecaller), ended up TNB replied my ticket saying no one picks up the phone. Their contractor is using strange name, hence as a normal reaction - ignore! haha Hope this helps. |

QUOTE(sgpdsmss @ Jan 9 2025, 09:30 AM) sorry what do you mean by 'which number' ?In mytnb website, under 'Apply' menu -> 'I want to check my application status', check if there is existing Service Request 'Change Tariff" or 'Meter Change" .. If none, proceed to raise a Ticket. A Ticket is better than calling them because you can always refer to the Ticket to check status of your request. |

QUOTE(adamw @ Jan 9 2025, 11:52 AM) If worry too much no need install. TNB enjoy collecting $$$. Cloud app down for all inverters does not means no generation, you can always opt for a 2 way smart meter to view the statistic. any recommendation on the 2-way smart meter , ie. Brand, cost, installation, etc. I presume it can show Total Gen, Self Consumption, and Net Export ? Thanks |

QUOTE(sgpdsmss @ Jan 10 2025, 10:27 AM) update ... good that you finally find the Status in Tnb Application monitoring system.6jan tnb status ..pending replace meter 10jan ....meter changed ... so solar system can go operation .. now waiting solaris rebate email ... thanks .... Anyway, meter changed doesn't mean you can turn it on, next is to wait for TNB Welcome letter which by then you would have another application called 'Change Tariff' ...

So, Micro Inverter or not ? This is one of the situation when Micro fares better I believe.
1 Solar panel is down and my vendor still hasn't come to fix it after I reported it 4 days ago. For this kind of a situation, you should be happy that you have MI instead of string ? If it is on String, it would have lost all generation I presume ? ![]() |

QUOTE(dwRK @ Jan 10 2025, 08:56 PM) panel has at least 3 bypass diodes... if shading or faulty, the affected section is bypassed... on Micro , the rest of the panels will still generate as usual. Tks for the info on string's bypass diodes.. Was trying to convince my friend why Micro would have an advantage here ..on a string system... you have normal production from other panels and probably partial production from the shaded or faulty panel... on micro inverter... the shaded or faulty panel most likely will have zero production because it has insufficient startup voltage... so a string system is better here... |

QUOTE(Cavino @ Jan 14 2025, 11:03 AM) Like that what is point of micro inverters in such cases..... some said one can opt to install "optimizer" for String setup in order for it to work like a micro's.. but i'm not sure if this comes standard or customer has to opt to add-on this device.One of their strength vs string inverter last quoted is 1 panel failing won't affect others while string inverter's panel failure might affect others. If string inverter can do the same (1 panel failing in the same wired group, not affecting others), then that so call micro-inverter advantage is muted. |

QUOTE(sgpdsmss @ Jan 14 2025, 02:07 PM) no wor....ha..ha interesting , would like to know if TNB accepts the extras generated.NEM Cert declared max 5kwac meaning max can export to tnb only 5kwac? my panels production extra 1.xxkwp may carry forward to next month ? Mine is on 3P, and my cert shows: Declared Installed Capacity (kWac) : 6.000 Installed Capacity (kWp) : 7.260 Also on Micro.. You can scroll back old pages to see why we never able to achieve 7.xxkWp as per your installed value.. Sifus said it is due to 'clipping' which includes many factors that prevent the output from getting the max kWp. |

QUOTE(sgpdsmss @ Jan 14 2025, 04:33 PM) pg so bad,never tell the true.. 3P = 3 Phase. So mine is 3 Phase. are u on single phase or 3 phase ? your Cert declared 6kwac mine single phase declared 5kwac single yes they allowed .. pg limit or seda limit? my seda Cert declared 5kwac only i asked pg, told max for single phase declared 5kwac ... so possible to change to 3phase and up the declared kwac? thanks ... If TNB has not rejected your total export, there is not worth to upgrade to 3 Phase. You may monitor your max generation to see what is the max your system can produce. Mine, peaked at 6.43kWh, that's the max it can produce from a 7.26kWp system, roughly 88% efficiency. You can monitor yours. |

QUOTE(cdspins @ Jan 15 2025, 10:08 AM) Alot of question... let's tackle one by one. Jus trying to understand more, so based on the data generated how did the system manage to generate > 6kWp ? Mine also 3 units of HMS-2000 which technically only produce 2000W each. Data below was captured via Hoymiles app.The solar panels max can produce 7.38kw if you have a matching inverter. But as your inverter is limit at 6kw, so your solar system can only produce max 6kw. Panel is just the panel on your rooftop, inverter is the one that change DC to AC. Solar power system is both the panel and inverter working in tendon. TnB will just take in what can be output by your solar power system. So in this case the max inverter output is 6kw. the 5kw is just a soft guideline for application. Extra 1kw form solar panels is can never be generated, because your inverter max output is 6kw. So you cannot use things that is not available. This is right! Maximum W from CSV 2024-10 6120 6.12 kW 2024-11 6068 6.068 kW This post has been edited by numbertwo: Jan 15 2025, 10:26 AM |

QUOTE(bee88 @ Jan 15 2025, 10:14 AM) Yes. Like I said, it’s all depending on the type of shading, which panel got shaded and how much the shading. But it will result in a lower yield generally when shading occur. Bypass diodes can help a little on panel level, but to ensure string system is optimized, it’s best to use optimizer so that the lower panel will not affect the output of other panels. But need to consider the cost vs the efficiency it boost too. After reading all these, it does sound that both system are equal in a small setup , insignificant to pay more for Micro. So , why Micro? only thing left significant is the ability to monitor individual panel ? hmmm..for example, if micro yield 10% more yield compared to the string counterpart, but the price is 20% or 30% more, then perhaps it’s the costing probelm. But if the price is the same, then it will be different situation. So it all depends on what offer u get. This post has been edited by numbertwo: Jan 15 2025, 10:28 AM |

QUOTE(bee88 @ Jan 15 2025, 10:47 AM) Max it can process per Port is 538.6w. So if ur panel is rated at 600w, clipping is around 60w during peak hours. yes i have came across 538.6w x 12 panels in a rare timing. But based on what cdspins explained, the inverter is max out at 2Kw each so the rest of the generated watts will never get out from the inverter. |

QUOTE(Genosyde @ Jan 16 2025, 11:11 AM) That 10kWac inverter is going to cost much more than the 8kWac one but the extra power generated will not be enough to offset the extra cost. so in layman terms.. having a smaller inverter will make sure it is working in optimum load when sun isn't directly on top of the head in most of the day time 12 hours. When the sun peaks at noon for that 1-2 hours clipping happens becoz of the smaller inverter, but it is just for that 1-2 hours. So why is the inverter always undersized? It's for the off peak hours. Say in the morning or evening when your panels are not generating the maximum 8.6kwp. Having 14 instead of 13 panels is going to help generate a bit more power during these off peak hours and the cost of an extra one or two panels is not that expensive relatively. Is this correct? |
