You should install the capacity based on your usage. What’s your usage currently?Home solar 4 months in.

QUOTE(ronnie @ Apr 1 2024, 07:54 AM) the max kW is cap by the capacity of the inverter's kW rating, right ? Depends on how you want your setup be. Don’t let the installer dictate what you should get. You should decide what you want. I would prefer a ratio as close to 1:1 Do providers typically size the inverter higher or lower than the total panels kWp ? Usually they will give 1:1.3 or 1:1.25. The higher the ratio, the higher the clipping, and in Malaysia weather, you don’t need such high clipping. |

QUOTE(JohnLai @ Apr 1 2024, 03:46 PM) Current installation is very messy. Actually I wonder why u wann to do this when there is nem. How much does it cost u so far? Are the battery stable?Don't get me started with leaky roof and requires sealant etc....Not to mention buying non polarised breaker for the battery connection to the off-grid-inverter. I gonna wait for my EVE and BT cells to arrive first before making any changes to current installation. Should arrive in April or May if I am not being scammed? |

QUOTE(adamw @ Apr 1 2024, 02:50 PM) I don't agree with you on this. Clipping you need to see the inverters specification. Never models can even accept ratio up to 1:1.3 for panels. For our weather this will greatly help during the rainy seasons. Panels price is at thier lowest currently so no need to stinged on it. There is a reason why we don’t need clipping. Our weather is just different from 4 season countries. They have amost 6 months of autumn and winter. Meanwhile, from my solar generation, I see that we only have about 1-1.5months of rainy season. And that also not everyday. Also u must take into consideration their system is very expensive , so oversizing is a way to minimize the cost and increase yield during poor weather. |

It’s only for Tnb account holder.Cause I already purchased all the certified solar panels + inverters + breakers + rails + wires etc, all contractor need to do is install it and certify it. Takde untung banyak, mereka tak nak. Problematic Sinopoly cells, had to replace 2 cells before getting all 16 cells stable. Cost? Wasted RM3000 for grid-tie-inverter Growatt 4200TL-X which in storage room now. |

QUOTE(ronnie @ Apr 3 2024, 07:42 AM) If your actual usage of electricity is 700 kWh for the month Actually, the easiest is to get the import - export. If the value is positive, calculate the bill based on the lowest tariff and goes all the way up(Usage) You'll be charged first at these rates 1. 200 kWh at 21.8 sen 2. 100 kWh at 33.4 sen 3. 300 kWh at 51.6 sen 4. 100 kWh at 54.6 sen THEN, (SOLAR) deduct the NEM export (to the Grid) (eg. 500 kWh) 1. minus 100 kWh at 54.6 sen 2. minus 300 kWh at 51.6 sen 3. minus 100 kWh at 33.4 sen ![]() for example, import is 990 export is 700 so you need to pay 290 units 200 units at 21.8 cent and 90 units at 33.4 cent and some taxs and misc charges like kwtbb etan26 liked this post

QUOTE(netflix2019 @ Apr 3 2024, 10:39 AM) Actually i still tak faham what's the other way of calculation that give us more advantage? I remember there was a tered that said TNB screwed us over with the way they calculate that tip the scale on their favor. Oh. That’s the icpt charges. And another issue is why not NETT import je. Like 990 import. 700 export. Should be 290 NETT so it should not kena gst 8%, and qualify for icpt rebate. Now, y need to py gst for the 990 import. (Next600) And no icpt rebate. |

QUOTE(ronnie @ Apr 3 2024, 10:44 AM) correct. but the reason is not this. The reason is the import is still using the traditional method of generation.. coz the import is the electricity u use mostly at night. At night, TNB still need to burn coal or use other method of generation to produce electricity. hence, it is not considered green energy. |

QUOTE(teslaman @ Apr 15 2024, 03:10 AM) It is 1:1. The reason the reading is different between app and Tnb recorded export is because unde NEM, you will use what you produce first. You only push the extra to Tnb AFTER u have used whatever you need to use. For example, I generate 50kwh, and my charging of car in the morning takes 30kwh, so the Tnb record only 20kwh of exports coz that’s the only left that I have after charging. And this process is real-time. Hence, the difference. |

QUOTE(derict @ Apr 15 2024, 07:52 AM) So, what you mean is that its common? But what are the % of what is generated as compared to received by TNB? Or what is the % lost during the transmission or so? It is not LOSS. your production is feed into your DB, where it get distributed to the appliances. When u produce, Tnb meter won’t import because u have another source of electricity (solar). And when u produce more than u use, the extra gets pushed to Tnb as export. Do you know the reasoning behind(if there is any)? Only night time, u need to feed from Tnb 100%. |

QUOTE(derict @ Apr 15 2024, 11:18 AM) Good to know, i didn't know it worked that way without any battery storage. The electricity generated will be used throught DB before being sent back to TNB. It will be NEM CREDIT valid for 1 year. Expire every 31/12Will it accumulate? I thought those excess will be "earned" by TNB and not accumulated for consumer? |

Than quickly, do all the laundry, use dryer, find friend with EV and jom them to come your house charge their cars and bring BEER, Chips, Cakes and all the good FOOD. If u don’t overdo it, u will not have this to worry. Also, u don’t need to spend too much on the bigger system in the first place. |
