Batteries are a must because household loads will start and stop, causing large variations in the frequency and voltage loads, which will fall outside the UL-1741 standards, which will cause different components to disconnect from the system leading to a cascade and a complete power outage...

There's a guy on Youtube claiming to be able to power his whole home, charge one or more Tesla(s) and do it with two 6k inverters, four batteries and 12k of solar PV. Most of yall already know most of this. Some don’t. Not criticizing the approach here – just sharing a different approach...

It seems your recommend a charge voltage is14.5. The Bulk charge voltage - 14.25 The absorb charge voltage - 14.1 and the Float voltage - 14.1 Do I have this correct?

It seems they recommend a charge voltage of 14.5. A Bulk charge voltage of 14.25 An absorb voltage of 14.1 and a Float voltage of 14.1 Do I have this correct? I'm not saying I agree with any of it, I'm just reading and interpreting this yellow and white chart this way. Do I have this correct?

I have the same question. Actually I'd like to know ALL of the recommended charge/absorb/float voltage settings for this battery.

I have one of these batteries 12V/400 ah and I'd like to get this revised manual. I've noticed that SS no longer shows this battery online. Is there any chance I could purchase a second one in the very near future? When will SS make them available again?

Ironically I have the same question for the same equipment, I called signature solar to ask them about the cutoff/reconnect settings for using a Victron Energy Battery Protect. on their EG4-LL/400 12V 5120 battery. I was told 12 volts cutoff and 13 volts reconnect, which is setting #8 on the VE...

The Solark app doesn't work on my De-Googled phone - which was the first give-away that something was WRONG. I noticed when I was attempting to install it that the two language options were English or Chinese. Like it or not, acknowledge it or not, we have been at war with the PLA and North...

Our daily consumption used to be 103 kW! Johnny recommended we convert to mini-split air conditioning to save power, so we invested in a mini-split. It performs well and its certainly energy efficient but it doesn't heat and cool evenly. So doing some research I discovered that York has a new...

My "static" loads includes an Unraid Server, a Security server that feeds 12 HD IP based POE cameras and their respective switches and networking gear as well as managing Plex 24/7. In addition there are two refrigerators and a chest freezer, several cell phone chargers, numerous safety night...

After Johnny connected the critical loads panel, its routine for this 12k Solark to get almost 11k from the solar panels, distribute 8k to battery charging, 1.2k to the house (my normal "static" load) and sell back the rest to the grid (1.4k) . Once the batteries are charged (less than 2...

BTW - Thats my system Johnny is showing there....

I know what I know and I don't know what I don't know. Feel free to enlighten me by not only informing me that I don't know what I don't know, because I already know that. I also know that Mikrotik is a Latvian company, however most consumer grade routers sold in the United States are made in...

Just take this one and set it out in the field? And get an EMP shield? Really?

I agree with you 100%. I see no reason why a hardware manufacturer cannot offer a simple locally administered solution to be able to monitor one's solar system on a home network and NOT NEED internet access, cloud storage, a third party or a complicated web interface to be able to make sure all...

Telling someone they are clueless is not helpful. If you truly wanted to help someone like me, the village idiot, please take up the time to tell us idiots what we should be doing, what hardware and software we should be using, as well as how to set it up and keep the bad guys from plundering...

I've gotten NO RESPONSE from Sol-Ark.

I have to share this: Our smaller (original) seven year old system is a 4.1 kW system on the roof with 17 Mage 245 watt panels. The original setup involved individual microinverters and a Mage monitor that was connected direct to our home network. I could monitor it myself. At the 5 year...

The issue we have here is getting code approval to use these things in residential applications. Our RV is perfectly fine, because code enforcement couldn't care less about the motorhome, but our brick and mortar home - thats a different matter entirely.

You are right! In our RV the MK3-USB interface cable was designed in the Netherlands and made in India. The Cerbo GX and the GX Touch 50 were both made in Malaysia. Its probably safe to assume that the Multiplus 3000 was made in Malasia but I know for a fact that the three VE 90Ah batteries...

Yea, which is why I mailed a letter Certified Mail to the CEO of Sol-Ark - sharing my concern with the corporate decision to have China monitor Sol-Ark systems. Had I known this was the case, I would have waited for Victron Energy to finally come out with their highly anticipated UL approved 5k...

Great find! A pictograph of precisely the issue.

You are probably correct. Someone else told me that they are actually Chinese made, but so is everything else. My SolarEdge is made in China and all of my Victron Energy Equipment is made in China. They might be companies that are headquartered in Europe or wherever, but basically everything...

I use Mikrotik equipment so I can program my firewall to prevent things like this. You should take a look at RouterOS by Mikrotik.

Whats missing from this testing is the CS116 testing, which measures the susceptibility of the equipment from transients of an EMP burst. EMP (not EMI) is what gets absorbed by the various wiring and dumped into the equipment at either end. Its this high surge in energy (high voltage static...

Honey-Pot is what it was called in the Electronic Warfare business. Designing a sacrificial device that is designed to suck an over-voltage pulse burst in a direction away from sensitive electronics. In other words, giving that lightning bolt a less damaging path to ground than going through...

Ahhh.... I think I understand what you are suggesting. You are suggesting that anyone interested in purchasing a Inverter can forgo the added expense of getting an EMP hardened inverter by simply adding an EMP shield to your system? If that is what you are suggesting you'd be mistaken. Even...

Are you suggesting different hardware? When you say "get an EMP shield and skip all of the sol-ark branding margin" that makes no sense. What are you suggesting exactly? If you have a Sol-Ark system and have invested $8k in an EMP hardened system, there is no option to "get an EMP shield"...

The sure fired way to find out where your inverter is "calling home" is to go into your router and find the IP address of your inverter, then take a look at the IP firewall to see where the Src address is connecting to the Dst address. The Dst address is the server that your inverter is...

I wanted to mount a security camera out on the PV array and make it wired with PTZ functions, so we ran a fiber optic alongside the HVDC cabling in one conduit and ran a separate conduit to bring AC power back to the array for AC power at the PV array. Fiber optic is impervious to everything...

We recently installed a new Sol-Ark 12k EMP controlling 32x400 watt Q-Cell Panels. During the finalization of the setup and building a plant, we couldn't get the Sol-Ark to communicate with the monitoring servers through our wired home network. A phone call to tech support was interrupted when...
