Solar Power in SE Asia (With New Grid Power Stabilizer)

Here in SE Asia, the grid power is quite unreliable and fluctuates ALOT. Blackouts happen quite often (usually 1-2 times a week / 12+ hours at a time). Here it’s super hot and in the raining season (starting now), there’s often limited sun.

With all that being said, I just wanted to share my current solar setup in hopes it’ll help someone or spark conversations. I’ll be providing updates on performance and my thoughts each month.

About our solar energy storage system:

- 24 KWh of solar panels (44x panels total).
- 97 kWh of batteries.
- 3x hybrid inverters (36kw total output)

See pics below. Ignore the coiled wire on the floor. It’s not connected to anything. I just need to clean up.

So far this has been plenty of solar and battery ✅

During the day we have basically unlimited power and at night we have been running 2 air conditioners at full blast (we don’t have central cooling here/ each room has its an AC). At the end of the night we still have 60% battery left. I suppose once we move into the bigger house and have 3-4 ACs running at night, the system may need to charge from the grid. But, I’ll update as I learn more.

You can see we have a small space for the hybrid inverters, batteries, and sub panels. Because it’s small, we have a dedicated AC set to “auto” that’s turns on when needed (you can see it on the bottom right hand side of the pic.

The batteries are stacked 2 deep into the room. So far we have not experienced any over heating but, I’m certainly keeping an eye on it.

I really wanted to get a GRID DOWN REDOUBT at my place here but, unfortunately they only have US standard 240V / 60hz and not the 230V / 50hz we run here.

Anyhow, I’m happy to share and if anyone has any questions, I’ll be happy to answer.

Here are some pics of my system.

About our new power stabilizer


As the grid is unreliable, we recently bought a 20kva power stabilizer (see image below). It’s been pretty decent at leveling out the grid power (which is our backup for charging batteries during the rainy season). Before the stabilizer, the power fluctuates so much, it was too dangerous to connect the grid to the energy storage system.

You definitely needed a stabilizer under those conditions. Do you have adequate ventilation for the battery bank, or just an ac unit?

Great question! We have 2x 10cm tubes venting into a side room and also a wall ventilation fan above the inverters. It seems ok so far.

Just checking inlet ventilation is often a neglected feature during install that people overlook. In worstcase scenario of a thermal runaway on the battery bank its crucial to have exhaust ventilation outdoors, because of any toxic fumes created.
 
What are the record high temps for your area?

The record high temperature for the state of Kansas is 121°F, which is 49.4°C. Not counting heat index. With heat index its 136°F which is 57.78°C.

It gets about 42C (114F) with a feels like from 120 to 140F. Im originally from Kansas and it’s insanely hot here compared to Kansas because of the humidity. Kansas is HOT, this place is a sauna lol 😂 It’s one of the harder things about living here. The other difference is that there really isn’t a winter (around 80F in December).
 
So you get zero breaks from the humidity; aren't you lucky - I bet you miss 4 seasons! Atleast that sauna weather will help you sweat out all the bad stuff.
