It was suggested on a FB solar group that i should go with 2s6p for 70a .... apparently that is the most powerful ? I heaven't heard that before as the KWh remains the same... and more crucially i don't have 50' of 2/0 wire lying around

37 +/- 4% temp 25c

voc = 37 +/- 4% 25'c TEMP I'm in eastern NC

Guys Just about to put the panels on my new array rack. Please chime in on panel configuration .. I’m planning On 12 x 400w all in series 400/31v(vmp) = 12.9a(imp) 12x 31v = 372v (under my MPPT LIMIT of 450v) Fused at 15a Any draw backs to this over 6s2p ? I HAVE NO SHADE ISSUES Thanks!

Thank you for your patience

Why would that be an issue as the GW has a shore power connection already available which i use at the moment when battery bank gets low?

I have 2 Gw 5 AIO .. but have an opportunity to pick up the GT4 very reasonably.... So I took a look at this thread as advised. https://diysolarforum.com/threads/can-growatt-spf-5000es-handle-ac-coupling.76673/ So the grid tie inverter has to see a constant 220, presumably that's why they go...

Thank you

Guys I’m looking at adding a GT4000 opti solar inverter to my system .. it’s a grid tie but I’m wanting to connect it to the AC in of my growatt es500’s as a ‘generator’ Thus maximizing the draw from the GT’s constant AC output. Presumably I can set the GW function to ‘grid first ‘ Any reason...

Hey Guys Wondering if someone has used the es5000 just to charge battery modules from utility? Been through the options 001 Listed here....I'm guessing the real question is this.. Q. Is Battery charging ever considered a LOAD? SOL Solar firstSolar energy provides power to the loads as first...

Did you get to the bottom of this and do you use the PC software v2.1.9?

Hi Guys i had promised to give some feedback so here it is .... Mistersandals estimate " Total on paper: 3104W" was pretty fair considering the 1st string points south and the second points west with 1 panel south facing ... they are also set at 51' (from memory) which was the optimum at...

LIGHTS = NORMAL AND INDICATING BMS IS COMMUNICATING WITH INVERTER

Hey Guys flashing light on circuit board of growatt es5000- no fault codes ?? Only issue i can see is incoming amps should be 8.0 .. often just seeing 0.1 ?? When i shut down and power up ill see 8a but gradually drops off? Intermittent cloud ( voltage reading good ) Connected to jakiper 5.2 48v

Gents you have been great Thank you .. I will post pics when up and running

That's Great! So to summarize so i understand - Having 2 equal strings would net 2880w on paper By adding one of the 375 to the smaller panels pushes that to 3104w The volt difference is 16v ( is that an acceptable difference?) between the 2 strings Sunshine can you explain the purpose of...

Thank you , No restrictions on connecting the panels to the most efficient output. Max Mppt Op Voltage = 450vdc Max PV input 6000w Max Charge 100a AIO growatt 5000es 270w panels vmpp=36v - ISC= 7.9a 375w Panels vmpp =40v - ISC= 9.9a

Hey Guys I want another string and have been advised on another forum that the voltage difference is too much 1 string of 270w x4 (1080w) panels in series 4x43.6voc = 174.4v. 1080/174.4=6.19a And 1 string of 375w x6 (2250w)in series 6x48.8voc= 292.8v 2250/292.8= 7.6a What are the guidelines...

Just that the pro Jakiper doesn't actually say its a LionPH

Guys .. Can i use a EG4-LifePower4 Lithium Battery | 48V 100AH AND A Jakiper [PRO] Lithium Battery | 48V / 100Ah | 5,120wH Connected in a server rack ??

Thanks for your patience and input .. very likely going to get the growatt 6k so my diagram looks like this now ... 3S2P. Is this looking ok for the charger input and amps etc Next big question is wire size from panels ? Will it be just 10awg? My run will be 30ft max and i tried to use the volt...

I was talking about the solar charge controller ... I think i'm going to save the sungold power 6k INV for another project and buy a growatt 6k AIO or the EG4 6.5 120v single phase .. both are 1299 but include a huge input MPPT .. why pay a grand for the big victron charge controller ...

2S3P = Ok so that's 3 wires going into the SCC ... the victron (for argument sake) has only 1 inlet for PV so i'd need a combiner ? Other than the wifi BT options with the victron is there any reason they are so expensive .. they look cheap (manufactured in china?) i know people rave about them...

Thankyou Michael .. esp the comment on SE facing panels ... experience experience.. I already have the sungoldpower 6k but it is not a solar off grid. I'm unable to add panels directly to it hence the Charge controller. I'm guessing if i expand bigger i'll at a growwatt inv or something similar...

Hey any comments on the components i'm considering here... will be expanding to another battery in a month or two and obviously adding panels when funds enable me to .... (solar charge controller too small?) Please suggest optimal config of panels

Hey did you find what you were looking for?

Frick I wonder if you would make a small post with some pictures of what you use .. that sounds like a great addition

Ok so this is what i found if anyone else is a newbe and concerned connecting the bigger inverters ... Apparently for a 48v INV you need a 10w 470 ohm resistor to precharge the INV before the full connection to the batteries ... or a 240v 100w light bulb : ) Thanks for the link 420.

Looking for advise on the correct flexible cable from the shore power outlet to my sunpowergold 6000w INV obviously for max charging for the batteries (jackiper 48v 5.1 x2) Also as it has a transfer switch built in what cable should i use to connect to the ac out (inverter) and into a big...

Hey i'm in a similar situation with a sunpowergold 6000w INV and a Jackiper 48v battery ... the battery is currently discharged to 12v do i need to connect the resistor between the batt and INV ? can i use the lightbulb?

Oh my ... I'm even more confused ? The battery(48v) has a current charge of 12v so well depleted ... can i not just connect my inverter to it (has an in built charger and get going?

I saw on a vid by Will P that you need to connect a capacitor to it first?
