And what time from Inverter to Utility?

What you guys think about MOES ATS ?

Any ATS that can seamlessly transfer so that PC is prevented from restarting

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

Yes you are right it hardly remains in absorption mode for 4-5 hours since at around 7:30 A.M I connect the load (refrigerator that consumes almost 10 Amp DC) and at that time only 9-10 amps are produced by solar so battery remain at around 13V and then gradually reaches 14.4 volts after 2-3...

I dont understand how someone can set bulk and absorption invidually when both occurs at same voltage???please explain this point. As per my knowledge bulk charging continues until battery reaches 14.4 volts, then absorption starts at constant volts of 14.4 until current drops to almost zero and...

Can this higher voltage effect battery life apart from consuming more water?

1. SIMTEK® MPPT + Solar Charge Controller 2. There is no option to set absorption time only Absorption Volts and Float Volts can be set, following is my settings as per manual of Battery 1) Bulk Charge Volts= 14.4V 2) Float Charge Volts=13.5V 3) Array power is 880...

1. Infinite duration with heavier loads like Fridge which takes 10~15 amps 2. Without any load or small loads like Fans or Bulbs it takes 15-20 minutes to reach float charging mode once it reaches bulk charging volts, which is 14.4 in my case

Yes I have used 6AWG wire between MPPT and Battery and installed ferrules and crimped them properly

But here same current is coming in and going out, I have measured with clamp meter when 15 Amps are being drawn by load the current supply also matches the demand but even then 0.3-0.5 volts are dropped across battery terminals

I want to add something 1. When the load is applied, voltage drops across battery terminals despite adequate supply from PV, I can give you an example at peak power PV can provide upto 35 Amps DC @ 12volts but still if a load of 15 Amps DC is applied, a terminal voltage drop of 0.3-0.5 volt...

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...

To avoid overcharging, I lowered the bulk charging voltage Can you please guide how to equalize charge with an MPPT solar charger having no equalization function?

Yes I removed caps and checked each cell separately, almost all have a gravity in between 1200 - 1225

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...

Yes both Voltage and Current to be measured are within ranges but here current will flow in both directions like in the night time solar charge controller will be on stamdby mode and taking some current from battery so will the ammeter show that current also?

I actually want to measure current from Charge Controller to the battery

This Ammeter comes with 100Amps Shunt and it can measure current and voltage

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...

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?

Battery is new, purchased 2 weeks ago, the float voltage mode remains if I run light load like 2 ceiling fan or 2-3 bulbs but on heavier load the voltage increases to bulk voltage settings

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...

Noted Which type of fuse should be used?

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...

Almost final look of the project, now I have to custom build battery cables and connect fusebox

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...

Thanks to all who helped me out there now I can summarize that 1) charging current totally depends on battery demand 2) SCC do not forcefully inject more current.

Thanks alot you explained it very well actually I was asking exactly what you explained.

But if I add more panels than charging current will also increase, is this the case?

About 11.6 volts 40 amps (15 amps load included)

Yes its a tall tubular deep cycle battery, battery usage is limited only during night time for running fans and lights, in the daytime it stays on float charging mode. I forgot to mention also I run fridge on that battery but during sunlight (9 to 5) . It draws 15 amp dc.

But alone Mppt will not help? It will give what it gets?

Battery is Flooded Lead Acid, 12 volts 145 Ah , Solar panels are 880 watts combine and 80a SCC ( Max PV input is 1500 watts)
