Thanks!

Thanks, Keith.

Thanks!

A classic!

You have to add adjustments for cold temperature s and irradiance. Victron has a calculator for that at www.victronenergy.com/support-and-downloads/software down at the bottom of the page. Its called MPPT Calculator Excel sheet As a ballpark figure, make sure you stay below 120v using your Open-circuit Voltages. As I understand it, the MPPT charger will only pull what it needs and cap amperage there. On my 150/35 model it will never pull more than 35 amps. I believe that refers to 35 charging amps going to the battery, not pulling 35 amps from the solar panels

You are conferming my doubts about, data from victron are not so evident and ready to be understandable at the first reading. 120V is a good compromise to Vbatt+5V and 150V is acceptable but 150V maybe regards to Voc of PV.

The 48-volt setting is a general range of battery... the choices are 12v, 24v, 36v, or 48v. The precise charge voltages are set under absorption and float voltages. I've since upgraded to EG4 Lifepower rack mount batteries, they are still set to the "48v" range, but the charge voltages are much higher than the volt batteries.

@@ReelClearMediaLLC thanks!

thanks!

Yes, it should be "width"... my brain misfired.

The Victron will limit PV amps to 45. As far as voltage, you have to account for variables like cold temperatures. Victron has a spreadsheet that helps: www.victronenergy.com/upload/software/VE-MPPT-Calc-4_0.xlsm

I've never used either if those, so I can't tell you from experience, However Victron has a calculator on their website where you can see how many panels work with different chargers. See the MPPT calculator excel sheet at the bottom of: www.victronenergy.com/support-and-downloads/software You'll have to get the recommended charging voltages from Renogy.

As long as your Voc Max on both panels sums to less then 100v, you're good to put them in series. Do factor in a little overhead if your area is likely to get cold in winter, as this can push the Voc too high and fry your Victron.

The victrons are great chargers. What is happening with the growatts?

@@ReelClearMediaLLC when they get the battery's up to around 25.6 they stop charging , the battery symbol blinks showing fully charged. The only way I get the battery's to fully charge up to 27 v is to take all loads off the inverters , and let the solar panels or shore power charge only the battery's. I was wondering if a stand alone solar charger would do better? Thanks p.s. I have the charge shut off set to 27.2 in the growatt.

@@bianchispurs Check Setting 2 and 11 to make sure it's charging with enough amps in absorption and float mode. If that doesn't help, The Victron chargers are very flexible. Make sure to pick the right model for your batteries and solar...

@@ReelClearMediaLLC Thank you, I will check that.

If you are looking at a charger in the app, you might not see any watts if the battery is fully charged. If the battery is charging you should always see watts on the charger page of the app.

You can limit output current to 20A if you want, and charging setpoints to 12.6v if you want.

@@fratermus5502 thanks for answering, I was busy and away from KZfaq this week

Thanks for sharing.

VE is not supported on Windows platform via bluetooth unless you use a VE.direct to USB cable (non bluetooth). It sucks that we have to buy an andriod device (table) to do the simple stuff.

Maybe try updating your bluetooth drivers. There may be a driver package with more BT options direct from manufacturer of your BT chip.

I started with one array of solar panels and charger, added another array and charger a year later. Also adds redundancy in case of a problem with a charger.

I suppose it MIGHT work... You would have to find a charger that matches both your solar panel and your battery. Victrons need 5v more voltage for solar input than your battery voltage, usually requires multiple panels.

@@ReelClearMediaLLC Thank you!

no. it is a step down charger. not step up. if you have a 48V battery you'd need to build a 48V system. and having 2x 40V panels plus a 48V mppt charger would be a proper way of doing this.

Generally, yes. The voltage can be affected by temperature and other factors. Victron has a spreadsheet on its website. 35 amps is the most the charger will pull from the panels, even if the panels can produce more than that.

@@ReelClearMediaLLC so...victron mppt controllers can overpanel both voltage and amps then regulate down to their max SAFELY?

@@MyChannel-vm6dw NO! Overvoltage will fry the charger. It is more complex than just the VOC, you have to account for temperature and other variables. Download the calculator here www.victronenergy.com/upload/software/VE-MPPT-Calc-4_0.xlsm

@reelclearmedia4157 thank you!

To my knowledge 35 means the max *output* amps from Victron controller to the battery. For example 35A * 12V = 420W and 35A * 24V = 840W charging the battery.

This model doesn't have any DC load out. Some of the smaller Victron chargers do.

@@ReelClearMediaLLC so you use this only charging batteries ? How you run DC load then ?

@@imranraza1978 I don't need to run any DC loads directly. My AC loads come from the inverter, and when the battery is full, the inverter uses solar from battery buss bars, which also connect the Victron chargers. You could also use a DC/DC converter to convert the 48v from the batteries to whatever DC voltage is needed. I just run adapters for the few DC loads I have.

@@ReelClearMediaLLC thanks

Thanks!

Your welcome 🤣😂

8 AWG, mostly because the run is 150' long, so a bigger cable for less resistance and voltage drop.

@@ReelClearMediaLLC oh yes, that's true, 8 awg, would be the way to go. How much voltage and current do you have going into, your charge controllers? From your array

@@carlosreyes6448 The first array has 15 panels, 160w each. There are three strings, with five panels to each string. The three strings are paralleled using a combiner box.Voltage ranges around 90-100 volts, current average 10-20amps. My max power is around 1700 watts. The second array has 12 panels. Three strings of four panels each. Voltages average 80-90v, current 15-25amps, max power is also around 1700 watts.

@@ReelClearMediaLLC I'm thinking about installing 8 rec 420watt panels and running a victron 150/60, it's rated for 3440 watts, but not sure about the configuration I'm thinking about 4 strings, series parallel, but they are rated at 59volts voc, and 8.9 isc,amperage.

@@carlosreyes6448 Victron has a spreadsheet to help you design arrays for their chargers. Download at the bottom of the support page. www.victronenergy.com/support-and-downloads/software

If you're connecting with bluetooth, it may only allow one device at a time. If so, You don't have to uninstall the smart phone app just disconnect from blutooth

Check to make sure the VeConnect application is supported on android 12. It may be supported now as when I purchased my tablet I chose v11 for that reason if memory serves me

@@Gary-wh7ce i just tried it and now it's working 👍👍. super awesome I'm excited thanks very much

I guess it wasn't real.. They shouldn't be full of sand. 😂

@@ThisIsNotRealityBase used for cooling open one up.

That's 30 amps max into a bank of two EG4 Lifepower4 batteries... each battery gets 15 amps. Their max charging current is 100 amps each, recommended 30-50 amps each. These batteries will be fine.

@@ReelClearMediaLLC your missing the point.... FLOAT you shouldnt be drawing that much current in FLOAT. you either have crap batterys, crap BMS or as leak somewhere. pushing 1.7KW!! into a full bank thats not doing anyhting?? 1.7KW is not float current.

@@freelectron2029 Thanks, I forgot this when video was recorded I was using 6 chevy Volt modules(12S)... The BMS was crap, but with 6 modules, that was about 5 amps/module. Recommended charge was 49.2V per module, I was undercharging to 48V to give the batteries a longer lifespan. I've since switched to EG4 batteries, but I still have the Volt modules I'm going to use for some smaller projects around the homestead.

That's cool. Thanks! The ones I have (smart solat mppt 150/35) don't have a load out, only battery out.

Viewers range from beginners to experienced. Some may not know the value of using an MPPT charger.

Exactly right !

Always one😂

How's this clickbait?
