The Victron price drop reached New Zealand so I went ahead and got a 150/100 SCC as well. Now my lounge system's 3 strings all have Victron SCC's. 2800 watts PV total available. At least now I'm confident that whenever the light allows and the battery bank isn't fully charged yet or I'm...

Put all the battery negatives on to a bus bar then one bigger cable coming off the bus bar to the shunt. This will measure everything going in and coming out of the batteries.

That's the problem with the Epevers. They do it in the morning as well for the first couple of hours. They lock the voltage down low and they just stay on that until they can be bothered to get going properly. The Victron 520w SCC on the other hand just gets on with it and can be producing 3...

The best contact possible is a clean flat surface. Dielectric grease isn't going to improve that. Its only job is to stop moisture getting in.

That's why with hindsight I would advise anybody starting out to go straight to Victron gear. Most people will probably end up there anyhow so don't waste your time and money buying inferior products.

From what I've seen, it's quite a palaver to get a Epever MPPT communicating with a PC...

Here's a typical example that I snapped a photo of today. It was late in the afternoon with some cloud around and the system was trying to maintain float with some load on it. Battery voltage had already dropped to 13.36V which is below the float setpoint of 13.5V. A 520w string going to a...

The 520w array is 4 130w panels in series. The 780w array is 6 130w panels in series. The 1500w array is 3 250w in series then paralleled with another 3 in series. All on the same roof facing the same direction and the time that photo was taken all were in the same light with no shading. No...

So before resetting the breaker you had... PV 1.16A 13.44v 15.6w Then after resetting the breaker you got... PV 1.04A 51.59v 53.59w That's the same problem I was having with my multiple Epevers as well. They would randomly lock PV voltage down low and I would only receive a very low...

I don't see anything wrong here. The SCC has reached absorption at 14.2 volts and the watts begin to taper down as the battery is now full. If you put a load on your system like turning on something from the inverter, you will see the watts increase again to cover the load. That's all proper...

I will be keeping them as spares. Never know if I'll find room to put up another array somewhere one day. I could just use one of the Epevers until I get a Victron in.

I was just thinking the other day how I have been getting along fine with quite modest PV. (I have another system at the bedroom end of the house with its own 1.5kw of PV and 7.6kWh LFP bank, so 4.3kw of PV total on my house) When people started putting solar on their roofs, battery storage...

From battery busbar.

That's why I said earlier in this thread - the days my batteries are full before lunchtime, I feel grateful and content. My batteries are full and its running most of my household loads. Including the hot water cylinder 24/7. I couldn't care less about not using potential solar production.

I've been enjoying the long summer days of the summer solstice in the southern hemisphere. Though I haven't been complacent and sitting idle. Nearly doubled the PV going to my main house system and upgraded the Epever SCCs to Victron SCCs that do a much better job of harvesting every watt that...

My Epevers would do it under any kind of conditions. First thing in the morning. Clear blue sky. Sunburst as a cloud cleared away. Clear blue sky when a load came on. I even saw them both do it at exactly the same time once even though they are not networked together. It must be something...

They were new recently purchased units. They should work decently right out of the box.

Just about anything can be achieved if you throw enough money at it. This is what I would consider the ultimate system in a RV... I would highly recommend to go with Victron components (except for maybe the batteries). Being that it is modular and can add more at a later date if they find...

Blue stuff makes me hard!

Agreed. You can build redundancy into a system. Multiple strings running into multiple SCCs. And them feeding into a battery bank with multiple batteries. Then a handful of smaller inverters running off that bank rather than one large inverter. If something fails then only a percentage of...

No, the 50A and 60A and 100A Tracer AN series don't even have the load terminals. The battery outputs go to a busbar setup. When I was watching it seemed to be the sun coming out from behind a cloud that triggered it. That was the exact moment it happened anyhow. I'll see if I can get it on...

If you go with Victron components you could also add remote monitoring with a Cerbo GX. (since they want to keep Starlink on all the time anyhow) Their solar charge controllers are dead quiet and very reliable. Their small 12v inverters are also very reliable and have a very small idle load. A...

Updating the firmware to Victron firmware along with its accompanying hardware.

I would guess that they see more of the sky on a diffuse cloudy day. How steep are the S panels? Are there more trees or buildings on the south side?

I laughed at this comment... "Do yourself a favour - there are many many importers selling off cheap Epever controllers that are actually MPPT. They are cheap, some would say unreliable, but at least they ARE an actual MPPT controller and won't trash your battery. If you want a really really...

Not likely. Someone should have already pre calculated PV voltage at the colder temperatures the panels are likely to see.

Absolutely. The same applies for discharging as well. That's the advantage of building a larger battery bank. You can put more charge in and draw more load off and also it gives you a longer run time. It depends how much space for the batteries you have and how much you can afford. But...

If that was the case then no SCC manufacturer would recommend or endorse oversizing. They talk about oversizing as when the moment you have more PV going to the controller than the controller can output at the system's voltage.

The 520w Victron made 2.26kWh for the day and the 780w Epever made 2.21.
