Re: Which batteries?

This is not going to be of much use. Why? Well, some lucky persons happen to live very close to where batteries are manufactured. In those cases, transportation of the heavy items is minimal and the selling price is less, like for any commodity. In other cases, people may have system preferences for...

Re: Learning OpticsRE

Hello. In order to provide more help from me and others smarter than me, we need you to update your profile to include how many panels you have installed and the total PV wattage, how many and what size charge controllers you have, your inverter make and model, your mate 3 or 3S model, you hub size....

Re: New Radian question

Hi. With 7K of PV, you could add the Radian 8K and then start with Trojan T105-RE flooded lead acid batteries. Why these? American made performance and reliability. I use them in 4 strings (three is the popular maximum due to charging characteristics). This is what you need to know: You want to set ...

Re: arc-fault breakers in combiner box

Hello. A regular circuit breaker takes several miliseconds to determine if the flow of current in a circuit is above the rated amperage value of the breaker. If it is for that period of time, the breaker trips. Therefore, a circuit breaker is designed to detect elevated load conditions beyond the ca...

Re: Am I treating my batteries properly?

Hello. I use 32 of the T105-RE. This works for me: I use a hydrometer and periodically check the electrolyte from the cells when the SOC of my FNDC says 100%. (ie. fully charged). Even with a load, the SG is always in the green. I water as needed with only distilled water. My absorb and EQ are 58.6....

Can you please describe how the Mate3s connects to your router (what kind of Ethernet cables, category of cable, length, brand or custom made?). In my case, my Mate3s is plugged in to a 16 port switch by a 4 foot cable. This switch then connects into a second switch via a 120 foot cable. This second...

Re: Internet connections

The Mate3s and hub create their own internal network of DNS addresses. But to connect to internet, the Mate3s needs to obtain an IP address from either your router or cable modem. These devices usually have what's called built in DHCP server that doled out these addresses on a leased basis. That mea...

Re: Backup system failures, low voltage errors

Okay, I have re-read your posts. First off, in your initial equipment listing, you have 25 PV panels. If I read right, each has a Solar Edge power optimizer connected. This is a DC to DC optimizer on each panel to counter the effects of shading an array. The output gets to 2 inverters. One is a 6000...

Re: grounding the subpanel

Grounding rods forming a duplicate ground point should be bonded together and spaced apart from each other depending on their length. Best practice is to form a circle of grounding rods. I was unable to find any information on bonding of grounding rods separated by a specific distance. The purpose i...

Re: Backup system failures, low voltage errors

Ok. Since it now is becoming clearer that you need a lot of help. Step 1. Know your system. Begin by going online to Outback Power . Download manuals for Radian, gslc, Flexmax charge controllers, Mate 3S and fn-dc. The fn-dc does use breakers. Those large breakers you spoke about are the main breake...

Radian inverter: ground with ground rod (best practice is for 2 rods 8-10 feet apart. Ground wire from Radian will connect across these 2 rods. Sub-panel: Receives...

Re: Running on Mini-Grid what should settings be?

Buy an fn-dc and make sure you have 2 shunts or 3 installed in your gslc. Then use the outback power wire diagram , confirm the correct wiring from radian through gslc to main panel. You should see load being measured in optics. Also, turn off your non outback inverter and see if radian is supplying...

Re: Running on Mini-Grid what should settings be?

Your load center should have been pre-wired. It would include an fn-dc and 2 shunts.
Please confirm you purchased the pre wired version.
If so, find the Outback wiring diagram for the gslc and confirm your wiring to shunts is proper and fn-dc also.

Re: Running on Mini-Grid what should settings be?

You can only sell in grid tied mode when your battery voltage hits your sell voltage, plus your PV is enough to charge batteries, supply load and produce excess to go back into grid.

Not minigrid mode.

Strings of solar panels comprise an array. You have 9 strings, but don't say how many are in each array. And I have clearly outlined how you ground an array of panels.

Re: Solar Panel Grounding

Each array must be separately grounded. To clarify SCENARIO ONE: Suppose you have 2 arrays of panels, separated by some physical distance. You must bury a 10 foot grounding rod near the array, preferably near the combiner box which is hopefully very close to the array. From that grounding rod, you m...
