So upfront cost of home energy storage is too expensive and you want to have a simple life and have the basic daily power consumption. We can offer you the most cost-effective and reliable solution only for a few hundred dollars.
How we do it? Let check it one by one.
First of all, you will need a battery. It doesn't matter it's lithium or lead-acid. But in nowadays market, their price is not much different and for best results, we do recommend 12V lithium battery. If you have tight budget, then buy 1 pcs of lead-acid is ok too. Trojan battery is a good option and there are many other brands you can choose from. Just remember only choose the one with good warranty and performance.
Secondly, you will need a solar panel. There are many type of solar panel avaliable in the market and we recommend to use the following for our system:
Power rate: 240W
Working Voltage: 38.28V
Working Current: 6.28A
Open-Circuit Voltage: 45.93V
This is a foldable solar panel that can expand when installed.
And thirdly, you will need an inverter that can convert the DC power to AC for your home appliance and your cellphone. So we choose 1200W Inverter for this application.
The details of this inverter is at the link: https://bslpower.com/bs1200w-12v-inverter
The important details of this inverter is that it also have DC features that can charge your cellphone or small battery powered hardware tool with 12V10A, PD60 and QC3.0 port. Also with PV feature input range 12-60V, max charge power 240W.
So you don't need a Solar Panel controller, you can connect solar panel directly to this inverter and use the power from the Sun.
So how much power it can generate from the Sun and what appliance it can support. Let see the list below:
Typical Appliance:
-Led Light 2-4 bulbs, 5-10W, -DC12V
-Electric Fan (1 unit. 50-75W) -AC Fan
-Cellphone Charger (1-2 units 5-10 W)-Type A Charge Port
-Raido, small speaker (1 unit, 10-20W_ DC 12V
-Small TV (24-32 inch LED, 60-100W)--AC
-Wifi Modem (10-15W)- Wifi
-Rice Cooker (small, short use 300-500W)-AC
-Air conditioner (900W) AC ( optional to upgrade to higher power Solar Panel and battery to long time working)
We can see that the whole system is very simple and BSL Power can provide 2 years warranty on all parts from our factory and we will provide full solution including cables and wires.
