11kwp solar panel capacity
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

Ours follow like lhdn tax bracket?

Your export will count as consumption. 

Residential can have capacitor to balance the load during the demand period?

12 Jul - 5pm - TNB guy come for meter reading again, he take picture and told me my case is in urgent case.

12 Jul - 6.30 pm - Received the Email from TNB say NEM meter complete, and a bill for this month payment.

I just installed a system with capacity of 9.7kwp, 16 panels with 4 micro inverters. But found out that the rated power of the micro inverters are 1.8kw. So, theoretically the 4 micro inverters should be able to generate 7.2kw max. If yes, then it means that I can never reach the 9.7kwp installed capacity. Is my understanding correct?

then is it possible that we install solar panel off grid? perhaps we have a “switch” at tng that entering to our house after the better. when we turn off that’s switch we go fully off grid. so doing this should be not require tnb approval right?

then next is perhaps install a battery size 1 tesla car. then it should be sufficient to run at night time every night. that case we fully use solar without paying tnb.

possible done in this way?

My youtube feed showing a town/state in Australia... Where the residential solar users are being forced to pay Power station for storing their daytime energy.

That day will come for Malaysia as well, so be aware, yes, will eventually pay TNB even though we export to TNB.
Eg. We pay Google/Apple/Xiaomi/ Samsung to store our data.

Unless there is a way for Power station to monetised the over production of power in day time, and still maintain a baseline energy production/consumption during non sunny panels... They will eventually want to charge us.
The money we saved now, better be prepared to invest in Batteries to not have to pay for storage by third party.

Just my opinion, DIY is a lot or risk and work. You really need to understand the solar system. If one is already in this industry, by all means go ahead. But if just regular consumers.. I will not advise to take the risk.

If Shopee pricing is close to NEM then direct import will be cheaper then NEM?

How do you guys manage this degradation? sprinkler system?

On topic of Off-Grid solar + battery set up.

Assuming I have total of total 4kwh consumption a day, peak power draw of 0.5kw during equipment power up.

My calculation says I would need:
1. 100AH battery
2. 2 x 500w solar panel

If I throw in 50% DOD (Depth of Discharge), that makes it 150AH battery required.

Is my calculation about right?

Or 100ah is actually enough because during day time usage, most of the time the 2 solar panel will be powering the equipment and charging the battery.

There's diesel generation running 12 hours everyday so effectively the battery will get recharged with the generator power.

About 3.77 this month thus far. March highest which was above 3.95

Average since 1 Jan 2024 is about 3.6 sun hours

not temporary. want 24/7 so can off grid and use purely solar. with a battery to charge it during the day.

power usage maybe like at least 2 aircons worth blaring 24/7 in terms of power consumption  maybe that is a bit exagerated but the idea is not to worry i run up short in case i just want to use whatever without worrying about not enough power to last through the day, or have long downtime
