Hello, I like it that more people are thinking towards renewable energy as another source of power.
I remember owning on of such calculators in the late 90’s.
I think you missed e in one there.
The inverter should be connected to a charge controller to avoid over discharge of the battery which can damage the battery in no time.
I think you meant to type that we should connect the PV to the charge controller. Then connect the output of the PV to the battery or batteries that feed the inverter the direct current.
Apart from a deeper discharge period, another significant difference between a deep cycle battery and the standard car battery is the ability of car battery to deliver a short, large amount of current required to kickstart an engine versus the smaller discharge current over a longer period of the deep cycle batteries.
Also, I noticed you used 4 hours as an estimate for daily use, that was a tight estimate :)
So it means you only use light bulbs from say 6 PM to 10 PM? Though everyone can have their assessment that fits their schedule. I'd recommend that you change the 18W bulb to some low-energy bulb (I use 5w) so that you can use the bulbs for longer hours. Also, consider buying rechargeable fans; they are super energy efficient. Mine at medium speed takes only 18W.
Congratulations on your system, it sure does cost some money, but nothing beats the power you'd always enjoy when you get home after the day's hustles.
You are right. I didn't mention the connection to the charge controller. Is your charge controller stand alone.? My inverter has an in built charger controller so the connection is a bit less complicated.
So true about the battery. An inverter battery should be able to deliver over long period of time.
I plan on buying an energy saving fan very soon. I will also check for lesser energy consuming bulbs like you advice.
Actually I don't get home until around 8pm. I mainly use the light read before going to bed by 12.
Thanks for your careful perusal.
Ok. That's awesome. Most inbuilt charge controllers are usually PWM, I prefer the standalone MPPT type of charge controllers.
It is always more cost effective to run a low energy devices instead of upgrading the capacity of the solar power system.
You are right. It is better to cut down the energy consumption of each load so that the efficiency of the system can increase.
