Hello Everyone I have used 12awg wire from solar panels to charge controller the total length of wire is 70 feet but I am not getting good result so I want to increase wire guage. Now can I attach another 12awg wire of same length with this wire in parallel? Will it work or I have to install...

Hello everyone, I have an MPPT Charge Controller with a maximum input voltage of 145 volts and a maximum input current of 17 amps. The controller's maximum power rating is 1500 watts. I'm considering connecting two strings of solar panels in parallel, each with a Voc of 125 volts and an Imp of 9...

Hello Everyone, I have purchase a DC ammeter for measuring output current from Solar Charge Controller to Battery but on the internet everyone used this for measuring either solar panel input current or DC load current so I am a quite worried should I use this ammeter for the said purpose is it...

Hi everyone I'm looking for some input with issues I've been experiencing with my setup that I've recently completed. The battery was fully charged and the MPPT screen showing "Fully Charged" with constant float voltage of 13.5 volts. I turned ON the off grid inverter connected with same...

Hello Everyone I am starting my off grid solar project, I have purchased all required accessories and now its time to connect them but I am not sure about the best layout . I am using 10mm plywood sheet for mounting all these stuff. I have prepared a layout for you guys to give me some...

Hello everyone Today I added some extra distilled water in only one cell of lead acid battery . Now whats the solution ? Should I remove that and distribute in other 5 cells or left it as it is?

Hello Everyone, Today while cleaning my solar panels I noticed that 1 panel has developed some snail trails in 3-4 cell (pictures attached here) I am yet not sure about performance degradation I will observe this today but I am so much worried. Is this totally a due to manufacturing fault or I...

Is this true that if a Lead Acid Battery is placed directly on a marble floor it can greatly reduce its lifespan? If so kindly explain the phenomenon?

Hello Everyone I am trying to run a small fridge (6 cuft) on battery connected in parallel with an MPPT solar charger . The settings of the controller are Bulk Charge Voltage 14.4 Float Charge Voltage 13.5 My load is ~140W @ 12V and I have a Lead Acid 12V 140Ah battery attached in parallel with...

Hi everyone, I have Mppt solar controller having max input voc of 145 volts but in the owners manual it says that maximum 6 panels of 150~170 watts can be connected in series so lets say if each panel has voc=19 volts (i am taking on lower side) than it will still cross 145 volts limit, both...

Hello everyone, I heard from someone that MPPT charge controllers provide all the current or you can say raw power generated from solar panels to the battery regardless its capacity of absorbing charge specially during bulk charging stage, we can only control the current by decreaing/increasing...

Hello everyoneIs I am planning to design off grid solar system for my house but I dont want to mount Mppt , Inverters etc on wall as I am living on rent and my landlord will not allow me to drill so much holes into the wall so is it a good idea to use Plywood Sheet for mounting Inverter, MPPT...

Hello Everyone, I purchased a 12volts Flooded Lead Acid Battery last month having 140Mah capacity and installed in my off grid solar system, a brief overview of which is here, 1) MPPT Solar Charge Controller 80A 2) 3 X 180watt Solar Panel & 1 X 330 watt Solar panel connected in Series 3) Pure...

Hello Everyone, I am looking for a device which can shift input source from utility to Inverter and vice versa without any lag . I saw ATS available online but they uses magnetic relay which do not shift very smoothly. If a computer is connected, it will definitely restart with these ATS

Hello Everyone I have an off grid solar setup with 145 Ah lead acid battery , the issue is that the mppt charge controller does not switches to float charging mode if I run somewhat heavier load like a small fridge which draws around 12 amp dc and the battery stays at bulk charging volts...
