Well I think you are misunderstanding those units, you don't get kwh from an inverter but from a battery, the inverter wattage its the max watt appliances you can keep working at the same time, with a greater inverter, you will get more continuous watts for your appliances, but the capacity of...
Well, I ruined my battery using the default AGM settings on my SSC, low voltage cut off is usually 10.5V for those default AGM settings which if not right, I just changed the SSC to User-defined battery type and reset the Low voltage cut off to 12.0V to avoid damaging my next battery. You have...
I have installed this system in December 2019, following Will's All-in-One system guide.
Been using it to power my internet router and laptop when there is no electricity, and as UPS here since the electricity fluctuates a lot here.
Overview:
1 MPP Solar 812LV-MS 12Vdc 110Vac
1 Weize AGM 12v...
Yes, you can wire the batteries in parallel to get the same 24V and double Ah, just check your batteries specs and make sure your batteries supports parallel connection. Those units have a working temp range from 0 to 55° centigrade.
This unit supports up yo 2000w PV array(solar panels) you...
Will recomends 270W solar panels, they are cheaper than 300w, based on watts per dolar, 300w cost 345$ and 270w cost 262$, i wont buy the 300w for that price lol.
Also there is an offer for 3 270W solar panels for 629$ on amazon, that makes no sense lol, 2 of them cost 575$, and 6 panels is...
In short therms its the same, but usually the 200w panels has pretty similar voltages compared to 100w panels, and you can add more watts with panels in series without exceeding the the voltage ranges of the SCC.
Also, you have to consider what is the minimum voltage range of your SCC to work...
1) a 24V battery is made from 8 cells in series, you need one 24V 8s 100A for it, if you have multiple 24V batteries to connect them in parallel i think you will need one bms for each one, im not 100% sure though.
2) This is answered on this thread.
Go for option 2, max 2 in series, you should avoid getting near max voltages as its not safe. Also, your Vdc cant be lower than 30V or it wont start charging, so 2 in series will get you between 30-115Vdc and thats what you want for your SCC to work properly and safe.
If you buy another solar panel and get 3 in Series, 2 Series the connect those 2 in parallel you will have a voltage loss and you will end up with the same 400W, and you cannot connect two 3 series arrays since you will get 600W and that will exceed the PV array voltage that is only 500W.
I...
They are pretty much the same, the only difference is that the inverter says 1000w instead of 800w. Everything else is the same, PV max watts and voltage, etc. Here is a pdf from mpp solar.
Hi @Nova22 for bms check this page these are the ones they recommend, the one you listed come with very thin cables wich is not recommended, i suggest you to go for the ones they recommend as bms seems to fail a lot if they are bad quality.
Also, i wish to know if low temp cut off is mandatory...
1. Assuming Your 100w solar panels are 12V and have an open circuit voltage about 22V as usual, you have to connect them 2 series 2 parallel, if you connect all in series you will be near the SSC limits and that is dangerous.
2. I don't know, I just connected them directly without breaker or...
Is the hybrid the green one? those are for grid-tie, but Will said they come with that feature disabled so you can use it for off-grid, just make sure before buying, if you are not sure just go for the 2424LV-MSD, the white one.
About shipping, if you are from USA or America go for USA MPP...
You need one 8s bms for every 24v battery, if you want to get more capacity just get 8 more cells and another 8s bms to build another battery, then connect both in parallel.
I tried it, was a little tricky to get it to work, had to connect the cable multiple times. Im not using it right now because im missing a long cable, but ill get one soon to monitor the unit with my pc.
You should be able to use almost every SSC with these solar panels, you don't need to get less voltage. If you have a small SSC you could just add solar panels in parallel to avoid increasing the VOC but it depends on which SSC you will be using.
Currently, I have a small 12v system with a 40A...
It depends on your needs, 12V is simpler and safer to install, but if you have high Watts demand you should use a 24v system or even a 48V system.
I don't think you will be saving money with batteries, a 12v 100AH battery cost almost the same as a 24V 50AH battery and they will produce the same...
I can't see the max voltage of the renogy SCC, it just says max voltage = 25V but im not sure which voltage is that on solar panels to compare, i think you could get 2 of these panels then connect in parallel to avoid exceeding the max voltage, but let some1 more experienced to answer.
This can handle only up to 100w on solar panels, and the battery is very small also.
Im not familiar with those solar generators, i prefer having a separated battery bank, im currently using a MPP solar 12V, it is an All in one system it has a 800w inverter and a 40A SSC, you should consider...
Yes, it was on my Mpp Solar unit, but it seems that other SCC have the same default configuration for AGM batteries so i wont use the default AGM config on any SCC without checking.
You have to check your batteries max charge rate also, for agm its usually safe to charge at 0.2C rate, that means a 100Ah battery should be charged at 20A max, 200ah at 40A etc, so i think you are fine by getting the max 40A from your SSC.
This could change based on your battery specs, but...
I have this system with only 2 100w solar panels. If you want to get the max watt of solar panels I suggest you buy 3 160w solar panels and connect them in series for a total of 480w since 200W is not enough depending on your needs, for me, 200W is enough when is not cloudy, but when it's cloudy...
I have an 80A fuse for my system between the battery and the unit, I lost a lot of hours figuring out that lol, the typical amperage is 66A for this unit and the max is 109A as Greycat says, you don't want to exceed that voltage but you will have to protect your cable as well, so, you need a...
If you connect different voltages/Amp arrays in parallel or series you will lose watts depending on the configuration, you can just connect the 3 160W solar panels in series and you will be fine.
I dont know if it can be used without a battery, but even if it can be used in bypass mode its useless, imagine an UPS wihout a battery, your appliances will turn off when you have no grid connection or when the voltage of the grid is too high or too low.
Ive heard of some 'special' mpp units...
VOC is open circuit voltage, the unit has a 102V max, I don't know if it's safe to get 88V, that is near the max 102V, but I see that other users in this forum are using 4 100w panels in series for this unit with no problem.
You
Yes, you can configure it to auto-switch to the grid when the battery is in a certain voltage, or even using the battery only when there is no grid available. You can't use solar input to run your appliances without a battery, so having this without a battery is useless.
Ok, i changed the bulk charging voltage to 14.5V, float to 13.6V and cutoff to 12.0V, i think the inverter will use the 12.0V as a base and will calc the to a lower voltage depending on inverter load, based on the inverter manual here:
The mpp solar 1kva 12v is a inverter/charge controller, it is 500w max pv array, you could install 4 panels 2S2P, and get 2 100ah batteries and you are done.
Im interested on this as well, my Weize AGM 12v 100ah battery is dying after 4 months of use, it discharges itself in 1 hour last time just by using 2 routers. It its supposed to last all the night.
I dont want to buy another agm battery, but lifepo4 is not cheap, will these "12v" nissan leaf...
No, if you switch the inverter off it will remain off until you switch it on.
You can use the power saving mode for that, to keep the inverter off until it detects loads, but i tried it and it wont get on if the load is low so it is useless for my needs. I just turn it off manually when i need to.
I have a voltage regulator and the "normal" light on it seems to be blinking when i have the inverter on power saving mode with very low load (2 routers), that could be dangerous for the appliances
AGM batteries tend to lose capacity over time, the batteries could be discharging faster because they are losing capacity. If you DOD your batteries more than 50% they will last less, I discharged my AGM battery to 100% by mistake and now it has about 25% of its normal capacity, and its only 6...
I started using WatchPower yesterday to monitor the inverter, it was a pain to make it work, you have to make sure the cable is good and you have to give it all permissions on the firewall, also, if you reinstall it this will create a new register in the firewall apps, I had to remove it from...
I don't have these cells, but I read about them in the forum and I'm planning yo buy some for a 12V battery, they are grade A brand new.
Check this thread to find reviews for these cells.
Max pv array is 500w for the charge controller, im planning to get two more 100w solar panels to get 4S for 400w, but im not sure if is safe, these are the limits on voltages for this unit:
For solar panels to SCC just get 12 AWG solar cables, renogy has good cables for that purpose you can get them from amazon.
Also, if you dont want to make your battery cables you can always buy windynation ones.
Check Will's page for recommended wires.
If your SSC says 400w for 12V it should...
Im using the mpp solar with default agm settings, not sure what is the cut off voltage for that, the inverter only cut off the battery 1 time like 2 weeks ago, then it happened again and mpp solar indicated a warning low voltage battery, looks like the battery was discharging very fast now, last...
I see no problems with the SCC.
1) 31V is normal for a 24V watts solar panel, it does not mean that the batteries will charge to that voltage, it is just the voltage of the PV array.
2) Do you have a 40A breaker from solar panels to the 40A SSC? You should use a 50A breaker instead, also some...
I have a 12V system with 2 12V solar panel in series, they produce up to 40V, PV array voltage should not match the battery voltage but the SSC Voltage range.
