First, is there any problem with using a powerstrip as the A/C output from the inverter? Should sizing matter (I can hear the ladies laughing....). I would like to run a variety of things from here - refrigerator, office computer, sound system (receiver and speakers), fan and internet...

Thanks to all....have it sorted out....

Hello.....new to all this.... Putting in an MPP 2424 inverter with the following specs... It has a Max PV Array Input of 145V DC and a Rated power of 2000 W. My array would be 4-327 W panels, so well under the rated power listed. Panels I'm considering are Max Power Voltage - 54.7V and Open...

Thanks....plugged in last night and woke to find no incoming power from the panels... I am assuming that it's probably a faulty connection somewhere along the way at one of the MC4's....I've got 4 panels running 2s2p from the roof down into the house. I've got an MPP all in one inverter...

Finally at the stage to plug the panels in and give it a go.... Is it OK to connect the panels to the charge controller during the day when they would have current flowing? I have a breaker between the charge controller and the panels....

I was going to start at the inverter and work backwards, testing at each potential point of failure.....no sense tearing things apart if one leg (+ or -) is working fine....I'm looking for a safe and non destructive way to do this and my first guess is the MC4 connections along the way, unless...

The install manual for the charge controller/inverter (all in one unit) specifies the following: CAUTION: Before connecting to PV modules, please install separately a DC circuit breaker between inverter and PV modules. Model Typical Amperage Cable Size Torque...

I'm going to ground my 4 panels with bare 10 gauge wire....Is there any problem grounding this to the house main ground for my home electrical panel? Don't want to have to pound another grounding line unless I have to....

Any recommendations for a DC disconnect for the PV incoming line?

I would prefer the simplest solution....If I can do it with MC4 Y connectors and not have to worry about exceeding any electrical limitations, this seems far simpler and easier to me....I could use some advice here.....would taking the 2 X 2 set of panels run in series and connecting them...

Soon to install.....would anyone with the 2424 MPP all in one unit comment on noise levels? I can much more easily put this in a corner of the office if noise levels are low or go to more efforts to move the unit to another room if it's loud... Also, has anyone with these units installed a...

Hello, Working on where to place the all in one inverter unit....best choice is my office but I'd like to hear some commentary from people with this unit installed to see if noise is an issue....spoke with the distributor and he said the Hybrid is quieter than the standard unit (fan noise...

Panels are on the roof....approx. 25' from main electrical ground.

Hello, Brand new to solar and this is where I find myself after a sizable bit of research, with some questions. I would like to order the MPP Solar 2424 series inverter. It is listed as 145v DC OCV as the input max from the solar panels I am also considering Sunpower 320W solar panels...

Another question - I plan to run my PV wire (hot line) through a single pole circuit breaker before feeding it into the all in one inverter (LV2424). I think a 15A breaker would be fine but should that be a different number? I'm running my Powerwall 24v (3kwh) battery through a 40A single pole...

Newbie here as well....just curious - what did you use for your 15A solar disconnect switch between the panels and inverter? Thanks---

After testing, I'm getting 100v on the + side at the breaker box with the panels mostly covered. So I'm concentrating on the - negative end of the equation. How does one test the negative lines coming off the panels? I tested them for Ohms and got a reading of 150 from probing my 2 negative...

I'm testing the incoming + line before the breaker and the negative line at the inverter.

Think it's sorted out....breaker issue....

So I have this in my mind.....2 sets of 2 panels each, producing 129.8 v output voltage from each set, each set wired in a serial fashion. My inverter has an incoming limit of 145V DC. This is where my electrical overload concerns are..... I could then connect the output of each set of panels...

All is resolved. Bad breaker connection. Thanks to all...

The 40a circuit breaker was listed in the manual to have protection between the battery and inverter, so I'm not worried about that re: sizing....I just wanted confirmation on the 15a breaker....since I'm going to have a box anyway, I'm going to run the PV through a 15a breaker just so I can...

No, I had a bad connection coming in....that's why I tested at 100v before the breaker and nothing on the other side....Duh kind of moment when I just disconnected and reconnected both sides of the breaker...

I meant 2 - 2 way MC4 Y connectors - this would provide the positive and negative leads going to the inverter.....
