Good afternoon, how have you been? I saw that you used 30amps pwm charge controller for 3 x 300w panels
My current set up is 30amps 2 x 170w panels. I am thinking of adding one 430w panel so I can power my 110w freezer during the day. Would you advice to get Mppt charge controller? Or I can stick with my 30amps charge controller based on your experience
12v system

I have a 300W panel (less than 6 months used). I stopped using when i did major upgrade on my inverter system
It is for sale. I also have 60a MPPT charge controller, Alexa voice Inverter system (1.5Kw)

GerogeI:


Buy more panels first. Two 170w is equal to 1nos 300w almost. Your 30 amp can take 3nos 300W at 8 amps each. When you exceed this, buy 1 more to make it up to 120Volts in series, before you buy a large capacity MPPT Charge controller and Inverter, which can last you for years. 120 volts is usually the minimum operating volts for large capacity charge controllers.

Boss, i have a 120Vdc 4000W hybrid inverter, I have connected 4 500W panel (in series). I just got a 1hp inverter AC. I want to use it (during the day). If i am to add new panels (lets say 4), would you suggest in series or parallel?

Its SRNE inverter (24V 3.3Kw) Maximum Vdc is 500V

Increase the panel. 300W

Hello, new to the thread here, i'm thinking of setting up a solar connection just for computer setup (not connected to the house). I'm assuming 18- 20hrs of power without nepa power supply and on a full charge. This is my plan below

1x Gel Solar Battery (150ah or 100ah)
1x 900VA Pure Sine Waver Inverter
1x Solar Panel 150W/200W
1x 30ah MPPT Charge Controller

please do you think this setup is going to be okay for my needs?
i think my computer setup takes around 12 -20W

Hello everyone.

Please I was given this quotation for a 3.5kva set up.
I want to know if these are the appropriate equipments for the setup.


2 x 220 ah tashatubularbattery
4 x 400 watts tashaenergy panel
1 x 60 amps tashaenergy solarchargecontroller
6mm solardc cablepermetre
Battery rack
Trunking pipe, aluminum rails, nails and accessories
SPDs, breakers, changeover switch and AC cables
1 x 3.5 kva Viltransformerbased inverter

Are the solar panels enough to fully charge the batteries in a day?
Is a 3.5kva inverter okay for 2 220ah batteries abi it's too much?
Would it be better to use a hybrid inverter?
What would you add and what would you remove please

The panel will be enough. Yes hybrid inverter will be better
