Why is that, from what I have researched, it seems ok to share panels.

I have 16 zshine, 540w bifacial panels, and will end up going to 4 inverters, 2 pairs running in parallel, and was wondering what is the best methodology, or if feasible, to run all 16 panels to all the inverters. Should they be ran in string of 4 each to hit the 160v DC from them, or...

Was.looking between the growatt spf500p es, eg4 6500ex-48, or the sungold sp6548 Why the eg4 over the other two?

Was.looking between the growatt spf500p es, eg4 6500ex-48, or the sungold sp6548.

Thank you. I do.not need to, nor do I believe, will have the option to export back to grid. I was looking at the sungold sp6548, eg4 6000xp or the growatt 5000es. Any thoughts, or better choices?

Good afternoon. I am in need of some help in selecting an inverter. First, do I need off-grid, or a hybrid. And do I need to use EG4 Charge inverters with the gensets I have. One is a Northern lights 33kw, 240VAC. The other is a Pulsar 5.5kw, 120VAC. Solar arrays are as big as I can get...

I.will check out the 6000xp

Yes, they are 50 Amp units. I have two service inputs that required. So two units would be required.

The sp6548 allows ac input. So.is a hybrid converter I believe. The 5.5kw genset I want programmed to turn on amd automatically charge the batteries if they get low. Basically, everything else has failed and that is my backup. I need a hybrid as I have a 240v 50 Amp ac coming in

The 6000xp is off grid, so not an ideal situation. Or can I use the eg4 chargeverters and an off grid inverter. The solar and 18kpv I would prefer to avoid the cost as it will push me into the $12kusd plus territory. I would go the victron route w that price tag. Trying to keep inverters...

I am in the USA. Delivery location will be houston, TX area.

There are two gensets. First is a northern lights 33kw 240v marine, second is a pulsar 5.5kw 120vac marine

Good to know how intolerant they are from a genset. The solar array is the largest I can get given my external space constraints

Good morning. I am looking between the Sungold SP6548 and an equivalent Growatt unit, do not know the models. I need to have 4 total, running two of them each in parallel, for an output of 13kw into two different circuit panels, hence the need for 4 of them. Input to them will be either two...

I, unfortunately, will not have access to the underside of the panel.

Looking at using either 1010 or 3030

I have 4 znshine 540w bifacial panels I am looking at mounting to slotted extruded aluminum rails. I was wondering what is the best method for connecting this? In addition, the extruded aluminum will be installed perpendicularly onto two tubes of 1" stainless tubing. I was wondering if any...

is this still available?

I am located in Seabrook TX, 77586, and looking to see if anyone is available to help assemble some battery packs for my boat. I have 400 SMC lithium cells, which I need to be assembled into several 48V packs. I, unfortunately, do not have all the time I hoped to have to do this. There is...

what are you looking at per pack?

Thank you for your input everyone. I sat down with a Victron Premier distributor yesterday. The biggest thing I now need to redesign is the inverter. I need to go to the multiplus 5kw one and parallel 4 of them, or 6 of the 3kw units.

I would love to have one voltage system. But again, chaing out bow thrusters to 12v, or changing out engine controls and systems to handle 24v, is not necessarily easy, nor inexpensively done.

And changing out alternators is not really cheaping out. Adding in balmars, new brackets and wakespeed charge controls is approaching 8~9k. If it was a few hundred, or even a grand or two, I would be all for it.

It is why my system has two generators. One 5kw and one 33kw. Coupel in with 8~9kw of solar and about 65kw of energy off the alternators daily. For the AC, again, 3 different design firms came up with this. I thought it was excessive as well. But my 52' boat, with substantially less...

Solar system I did want to break up into 4~ 5 strings. I understand the AC system is huge, but 3 different firms came up with close to the same tonnage. Some used all in ones, some came up with a chiller/air handler combo. Batteries, I may just go with 100kwh of rack mounts to make life...

Sat down and did an estimated energy audit. It comes in at 65.2kwh/day with no AC, with AC 161.4kwh/day. So the 100kwh house bank is appropriately size The alternators on the engines I plan to charge the AGM's and hope to come up with a solution for the AGMs to apply power into the house...

Running the A/C's off separate panels I have put a lot of thought into it. I do not want to run the generator to power all my 240 loads, and do not want to run it anytime I have to run the A/C's. If running all of them, then yes, on the generator. For the headway cells, yes, I can run them...

Thank you for the input. 1. I agree on the too many batteries not doing lots. Unfortunately, they are dispersed throughout. The AGM starters are in the engine room. The batteries for the windlass and bow thruster are in the forward bedroom. The batteries for the stern thruster are in...

I am know I am very tight on solar. I do wish I could add more, but unfortunately, I cannot, unless I want to get rid of my dinghy or remove seating from the bow. A/C needs are high, but the dark hull, going through the Caribbean and Gulf will add enormous amounts of heat. The goal is to...

Thank you for your input. It is a block diagram, from there, I intend to make a much more detailed wiring diagram. All systems on the boat are/have been done that way. For the energy audit, unfortunately it the 6 AC units with a combined capacity of 10.5 tons, and going through tropics for...

I looked at the alternators, but it would add significant cost, around 8~10k to update alternators. Not worth it, to me. I have 8kw+ of solar, and a 5.5kw and 33kw genset onboard already. No need to add additional cost for something that will not generate a good enough ROI for me. My...

Here is the main breakers for this system. The left hand column is all for 240v and the middle and far right are for 120v.

For the 24v and 12v loads, most are tolerant of voltage variations, as they are built for this application. Some, for example wifi routers, put in a regulated 12v output regulator. It will take +/- volts and give me a constant 12v, 24v and 48v (POE equipment). The windlass I believe draws...
