Go youtube look for 18650 powerwall projects if you're comfortable with lithium technology.

Go youtube look for 18650 powerwall projects if you're comfortable with lithium technology.

i am , but that battery pack is a bit too much for me right now, i still have to play with BMS first. And BMS is pretty costly , a 16 cell BMS is roughly 1k and then slaving each pack to a main BMS is another level of complexity

Well, few month ago I started building this new unit at my house after selling 2 of my motorbikes
2 motorbikes which i rarely used sold for this Rumah Solar building expenses and extra money I bought Electric Bicycle

Slowly the house now is going Fully Off-Grid (The Container still using TNB supply) and the Rumah Solar (My Office) Fully Off-Grid
The new Rumah Solar will be my new office to do Renewable Energy Business and web development, where I allow people to come and see the real life system (how it works etc)
And the power generated is used to Power all appliances inside the house and charge my electric bike

Underneath the house I used it as shaded parking space for 2 compact cars



So, let's watch this intro video, more coming soon:
Cost: RM13,800 for Solar System + RM15,000 for the House + e-Bike (Bought directly from guangzhou)
Now in my possession 2 electric bikes + 1 compact car, looking forward to own an electric powered car if got enough money haha (which still a dream far to achieve)

Almost accidentally burn my finger.

During solder the minus terminal side, the long solder lead touch the bottom 18650 + side cell. While my finger holding the lead. 

Instantly the solder lead melt and my finger holding the lead feel the burning. Immediately flung away the lead.

Lucky the lead act as a fuse. Otherwise will get burn mark. 

Have to handle very very carefull for lithium.
