Equipment list corrected ! Yes two blocks connected in parallel which is the maximum recommended and I have set charge current @ 20A but will change that . Put Batteries in today and switched system on just as sun was setting to be safe as I wasn’t 100% confident in my set points…turns out they are...

Please check your profile and update the equipment list. A VFXR3048(E?) is listed, but its mentioned the system is 24V. How many of these 24V @ 100AH battery blocks are being planned? Does the BMS permit parallel connections? IMO, at least 2 blocks (24V @ 200AH) is a minimum. Looking at the specs, t...

The entries under Port look to be "legit" LAN addressing. Confirmed by being able to access the Mate using the IP address displayed. The entries under Ethernet Addresses would not work. Perhaps they were manually entered at some point? DHCP Enabled, so the Port addresses are likely configu...

Once done pushing buttons and the system settles down, I'd be curious if you're seeing battery charge event log entries akin to this:

For your battery, charge current is to be limited to 75 Amps. "Is this the case with two SimpliPhi batteries?" Yes I don't know about the Grid Tie Mode activity on the Mate3s, as I never had occasion to mess with it, except that the FX3048T isn't "grid interactive" so maybe the ...

I'm not 100% sure what sequence of configurations have occurred (but have an inkling.) For Global Charger Control, three parameters (and ONLY three parameters) are enabled: 20220518_163038.jpg FM80 Misc -> Grid Tie Mode = Enabled (Note its disabled here) 20220518_163111.jpg Mate3s Global Charge -> G...

Check all the disconnects (circuit breakers) and make sure they are in the ON position. Were any wiring or configuration changes made recently? What type/brand/model battery? Looks like the battery has been charged (by solar?) and the FM80 is currently idle as it has nothing to do. Also, the inverte...

I assume with such a small battery, run time is limited. Another consideration is the maximum charge current the battery will accept. AGMs have relatively low internal impedance, so accept a relatively high charge current, but there is a limit. A flooded lead acid battery may be limited to 10-15% of...

Disconnect PV, wait until FM shows idle (Snoozing, Sleeping, etc.), then reconnect PV to restart the FM80. Make sure you have Current Limit set to 75A. At 54.8V the battery is above Float voltage, so if the battery has been fully charged (check the Event Log), the FM has nothing to do at the moment....

GM raysun, not sure if a new topic is required however, my CC is in "GT Mode"...and I'm off grid. I have doubled checked everywhere in the Mate, Inverter, CC and FNDC for settings relating to Grid Tied and made sure they were set properly, and they are now however, CC still showing "...

If the math is easy, why is it wrong in the original post? The stated design goal was a 10000AH battery. Obviously impossible with 5 200AH monoblocs. When a 60V battery was configured did the inverter start? Nowhere in the GS8048 documentation that I could find does it state the inverter charger sup...

I was using 4x12 200Ah AGM Batteris in the "48Volt" configuration and wanted to add a another battery to make the battery pack 10000Ah. now the flex charge controller has not problem with the absorb voltage of 73.5 or the float of 68.5V. but the Mate3a for the inverter GS8048a will not go...

I wish you good luck in finding a servicing vendor. If its like our area, and most areas I suspect, companies only service what they install. The general reasoning is having no input into the design and installation, vendors have no control over what they would be getting into. Also, service calls t...

Everybody else. OB is working on it.

I would trust the string sizing tool. The person doing the code for that knows what they are doing and purposefully allows the limits, but I understand if you are concerned about it. Maximum power or maximum DC/AC ratio can be important, but most important is the Max Isc (in the manual) and Voltage...

Keep scientists the he77 away from the system at all costs!

Check the event log. It will have captured the charging steps.

the inverter's current limit is set at 50 aac...should I increase it to 75 aac ? Goodness! Is your generator that large? Your inverter isn't designed for that AC load IIRC. There are two AC Input limits to set: 20220516_123511.jpg • Gen Input AC Limit This should be set at (or below) the maximum ra...

what would be the negative of putting PV back online to help with charging The maximum continuous charge current for the battery is 75A. How much charge current is the inverter delivering? Has Global Charger Control been implemented? When the battery reaches the Absorb Voltage set in the FX (56.0V)...

generator charging for 1 hour and 15 min and Mate3s is going back and forth from 53.9 to 54v. Charge controller reporting 54.3v This is pretty normal for charging. That voltage range is the "plateau" at which most of the charge takes place. The 150AH battery was likely at or under 20% SoC...

It will take a good while to get up to full.

Are the Phis the black plastic case blocks, or the white metal case?

Our panels are permanently mounted flat (actually a 3% roof pitch so rainwater runs to the gutter). We don't have the unattenuated clear skies San Diego enjoys. Its rare to have blue sky here all day. Rather, we have clear mornings and partial cloud cover by about noon. We could squeeze more PV harv...

The FNDC won't be accurate until its: • properly programmed • connected battery is actually charged to 100% The Absorb voltages on the FX and FM should be set as posted earlier (56.0 and 56.4V) respectively to establish priority for solar charging in the event both are being used at the same time. A...

Great, I changed Absorb specs on FX, FM and FNDC from 54.6v to 56.4v. I also plugged FNDC back up. I will investigate "trim pot" and using FNDC for LBCO for inverter in the morning. I have learned a lot today thanks to you Raysun and my neighbor. Thanks so much for having the patience...I...

LOW BATTERY CUT OFF USING THE FNDC The FX inverter LBCO parameter cannot be set to the 50V cutoff specified for the Phi battery. The FNDC's voltmeter can track battery voltage, and its relay programmed to switch from a closed (ON) state to an open (OFF) state. The FNDC can control the FX Inverter ON...
