if its just a 1 battery setup...then it will always fail within 1,2,or 3 yrs... as most users usually exceed the manufacturere recharge cycles soon enuff. 2 batt setup also suffers the same fate...
only way you can prevent such is if you have an intelligent inverter with dod switch..wch u will set to 40 or 50% so it stops draining your battery when it gets to that level.
a 12v 200ah battery contains roughly 2kwh energy factoring in losses and inefficiency, at 50% dod u now hv 1000w, so it can only power a 100w load for 10hrs, 200w load for 5hrs, 300w load for 3hrs etc

In addition...
If you discharge at higher amperage you get lower back up time 100w load will give you about 11 hours, 200watts 4 hours and 300watts about 2hours...

A 20HR rated 200AH battery should not be discharged at more that 130Watts (10A)
If your load is 300watts then recommended battery is 2* 200AH

Oga Pranil, verily, verily, I say unto you, all Controllers are not created equal - you can safely oversize the Morningstar multiple times over the rated PV wattage - although anything over 200% overrating, I would struggle to see the benefit and call it inefficient design.

For the EP Solar E-Tracer series, the manual states the Maximum PV Array Size = LBatt * VmP where LBatt is the maximum battery charging current and VmP is the PV maximum power point voltage. For the 60a EP Solar eTracer used in a 48v nominal battery setup with the common MPPT 3 x 3 config (3 pieces 24v nominal panels in series), that would yield LBatt 60amps * VmP 115volts = 6,900w as the maximum PV array to use (I think the manual specs 6,300w sef) - because there is some play around what the VmP may be for different panels, to be safe I would stop around 6,000W PV array size .

I have no knowledge whatsoever of Midnite because I don't like it and have never used it - a pet beef you might say grin I will let the users and pros tell us what the maximum safe PV over size is if any.

Between, how do you paste pictures so that they stay in the body of the text? I have tried the [img] [/img] tags but only succeeded once - I want to paste an excerpt from the EP Solar manual just like you did.
Very true.
Try substantial oversizing with epSolar and one would soon be shopping for a new CC.
Re: Solar Energy, A Complement To FTA by Saipro(m): 9:34am On Oct 27, 2017
pranil:


No amount of oversizing should fry a MPPT CC unless you exceed the VoC. The CC limits the output current to its max rating. Although it is not a good idea to run CC at max current rating as the ratings are usually 40 /45 DEG ambient. and in Nigeria, we can exceed that in closed spaces

The morningstar is notorious for frying on battery breaker trip as it's Transient surge rating is very low. The correct way to restore the system in such a situation is to trip the PV breaker - Allow the CC to cool down and dissipate the residual charge ( usually 5-10 min) switch on battery breaker wait for a minute and then PV breakers one at a time
It is also a good idea to set the battery voltage to fixed value instead of autodetecting especially for 24 and 48 V systems as the CC can be set to a wrong value if you switch on battery and PV in rapid succession


reference -- Quote "
https://www.morningstarcorp.com/advantages-morningstars-dc-coupling-vs-ac-coupling-whitepaper/

You can size Morningstar’s MPPT controllers well above the Maximum Nominal Solar PV Input rating without damaging the controller and without the charging current exceeding the maximum output current rating. The controller can limit output current and will run at 100% of rated current output and not higher. The controller was designed with this power-shaving capability and when oversized it does not void the warranty.” – Tech Article – “Morningstar’s TrakStar™ MPPT Technology & Maximum Input Power”

@Zeestone99,(Already chatted a bit yesterday) GeorgeD1 (has the most extensive SP project here I think)

Please, can I indulge your knowledge about building a good solar power project.

I have read and still learning about SP. I am looking for one in excess of 4KW plus or more (if needed)to run a bungalow or two. Items such as fridge, tv, low energy LED, washing machine(?), microwave (?)

Say I had the opportunity to purchase all I wanted from abroad at a fairly cheap price, would that make a lot of difference versus buying all from Nigeria?
I have possibilities of getting for example
solar panels
deep cycle batteries (from AGM to lead acid)
Inverter

Would just like to draw on your knowledge on what could be bought to make this set up a very good and worthy setup.

Here are just a few reasons why you should Stay connected to the world, be Comfortable at home, work efficiently, preserve perishables, give your loved once the best.
Getting results and taking charge of your life requires you cutting your own part despite the challenges.
stand out from the crowd , power generation is too expensive, constantly buying fuel and repair of generator ,waking up to change over when light comes ,the noise their just has to be a better way to save money on energy bills, be more productive ,have a better resting environment enjoy fun with family and loved ones.
We can imagine how inconvenient it is to generate your own power, coupled with the cost to maintain a generator and the problem of buying good fuel which isn’t readily available and then the noise ahhh!!!.

Your mppt has no issue.. It depends on your preset value & timing for charge hours . if you tamper with old boost/equalization setting of 60 min to 1 hr or above , it stays on boost for longer period of time before reaching float mode ! You can freely contact me for other enquiries ...

the cc will do better if you double/series the panel voltage. For you to achieve this on epever you have over 300w of panels

Just a test run, Panels are quadruple that power.
i believe series/parallel don’t matter for mppt
because power cannot be created or destroyed
just converted from one form to another
if u do the calculation; it amounts to the same power whether via series or parallel
i might be wrong though.

Yes, it amount to the same power at the point of generation, that is, Panel end but different at the CC end due to cable loss.

Parallel connections will result in higher current, lower voltage. The higher the current, the more the power lost in the cables

Series connection will result in lower current, higher voltage thereby minimising the power lost in the cable.

If you are not using appropriately rated cables for the installation, the cable loss can be very significant.

Epever users I need tips and tricks

I just Got EPEVER Tracer 4210 A , SHI 1000 Pure inverter, Wifi Box , USB cable and temp sensor - all 24 Volts. In preparation for my wind turbine experiment, 12 V 150 AH AGM . The idea is to use my excess equipment to power BQ independently and feedback excess power to main house using Ac coupled grid-tied micro inverter

Two 300 watt wind turbines on their way

On first look, I am disappointed on multiple fronts

The Wifi box does not work with inverter but works with charge controller ( both have RS485 com ports)
The USB cable works with Inverter but not with charge controller ( explanation next point)
For PC there is no software for setting monitoring for charge controller ( only android - not even in play store )
For inverter, there is android software but since the wifi box does not work ( not even powers on) no way of checking
No back light on CC at all ! not even with a button

The whole software experience is clunky at best. The hardware looks nicely built through with proper heatsinks and terminals etc.
Managed to make 1.5 KWH from my old 600 watts Chinese no brand panels ( rebuilt junction box, corroded tracks etc.)
