Who has used this and how long does it last. I want to use it to power just my Hisense 43inch smart tv. And does it need much installation since I know nothing about it.

Won't last much. If budget is an issue, just buy an MPS2 from CooldipoMPS, add panel and you will get decent hours of usage.

Well said! Thanks for the mention sir!!

I don't think this is the current price.

Besides the system is for very light load

Hi, I'm new here and need guidance.

I have 3 computers which I need to keep running 24/7 because I'm using them as a server cluster. I have purchased a 100amp pwm solar charge controller and I have two batteries which I can use for this project. Details of my load and batteries are below.

1. Raspberry pi 5 drawing 5 volts 4 amps

2. Raspberry pi zero 2w drawing 5 volts 2 amps

3. Mini ethernet switch drawing 5 volts 1 amp

4. One single 12 volts 90 ah lead acid battery

5. One single 3.2 volts 72 ah CalB LifePo4 battery.

Those are the items i have on hand right now along with the 100 amp pwm charge controller. Please I need to know the right size of solar panels that I can purchase and wire up which would be able to provide enough power to directly supply current to the three devices I have as loads above during the daytime and then be able to recharge any one of/both of the batteries I have to be able to power the loads during the night when the sun goes down.

I am a complete novice in electrical matters but I am willing to learn. I do not have any cash right now to purchase an additional battery so I need to make do with the setup I have on hand right now and plan for an upgrade soon. I just have to purchase the right solar panel size and type to give me the juice I need to at least power my devices during the day and then I can depend on whatever my battery backup can give me at night for the time being.

I am in Africa, we have good sunshine most of the day. All my devices arr rated at 5 volts max. I fear I bought an oversized pwm charge controller for my setup (100 amps) hence my worry that I might have to splurge on solar panels to feed such a hungry controller.

My humble questions are thus, can I use a lower rated solar panel with the 100 amp controller? Is there a minimum wattage of panels that can be used on the 100 amp controller? Will it hurt the system if I under-feed the controller power from the panels? I don't think I have the cash to buy anything more than a 150 watt panel at the moment but I desperately need this system up and running one way or the other.

Thanks all. I appreciate your advice.

The battery was 255,000, 1.5kva inverter was 215,000.

These are Port Harcourt prices, might be cheaper else where.

I use a 580w Jinko panel to power the ba3. And I make sure I don't use the ba3 below 50% before the next recharge.

So when there's no assurance of NEPA light at night, I only use lighting points when necessary, my inverter fan and charging of phone and laptop.

NB: I can use the table top fridge and the washing machine together, but I don't do that because it's just one ba3. So if I'm using one, the other has to be off. However, in the afternoon when there's sun, the 55w fridge can be on alongside the 43inch TV, decoder, and home theater. All these combined only amount to about 20% load on the inverter.

And I do this only when the charge controller shows a float charge.

Please sir what type of battery did you use

Boss abeg, the MPS2 pro & mps3, if one pairs panel with it, during the day when the batteries are full can one plug load directly to the panel+inverter?

Once your battery is full,the solar will almost directly powers your load automatically
