If it's a top-loader with a single-speed induction motor and transmission in it probably needs a soft-start to manage LRA maybe a bigger run capacitor to keep reactive loading in check. An inductive AC motor in a washing machine would be a pretty savage load for a high frequency inverter to...
With most breakers, the supply side is generally at the top (on-side), so the photo shows the battery supply connected to the load side, which doesn't appear to be compatible with the schematics of that model number. Some DC-only breakers allow for interchanging the supply and load side when...
I was reading what you said about your NEM 1.0 Permission to Operate agreement expiring. Even if you end up with eventually nothing back from your agreement, the Grid could still be a no-cost diversion load, couldn't it?
I read through the 6 pages and it appears the issue is ongoing regardless of firmware levels. I gather that you were waiting on a net-metering agreement with the utility that you didn't initially have, but now do have, and can enable sell.
If your buyback rate is 1:1 then there is no incentive...
I ran a 90 Farad automotive supercapacitor with my Trace SW2512 for years before decommissioning that inverter earlier this year. It legitimately reduced the rapid pulsation of charge/discharge to and from the battery as the inverter created the AC waveform. Without the supercapacitor, a...
Dear Schneider,
The ecosystem of available 48V devices continues to grow along with the likelihood of more things being connected to the DC bus of a Schneider Insight system.
Please make a Xanbus configurable AUXILIARY SHUNT CONTROL INTERFACE for Insight so we can monitor and log DC power flow...
Have you tried using diodes on each string?

Do you have a PC set up with a serial port connection to the BMS in the EG4 batteries? A battery BMS that is faulting into disconnect can cause both the DC undervolt and overvolt errors you're getting. As was mentioned, you might have a few cells out of spec that the BMS isn't able to...
That is awesome. Wish they'd make it in a 24-cap version for 48V DC nominal systems. Looks like rated voltage is 48.6V with surge up to 51.3V for the pack. My system is hitting 59V daily and 62 during equalize. Would be comfortable manually disconnecting it with a breaker during equalize...
DC breakers are polarity specific because of a magnetic component involved in preventing arc when tripped - and that can only work in the right polarity. A 2P breaker allows for bi-directional protection because the two poles are wired in reverse polarity from each other. In that way, no...
Any batteries in series, of any chemistry, need to match each other in spec and lifecycle. The main concern with different capacities in parallel is minimizing millivolt differences between the batteries under load.
For example, say you have a parallel battery bank consisting of:
- Two 230Ah...
Referring to sometimes registering current flow, sometimes not, and then an end user being told to reverse the "polarity" of an AC input. Just reading along here, it's what I like to do instead of watching TV.... read: nerd! If there's a fault or problem at the root it seems like getting it...
Yes, but only when connected like the diagram shows in the 2 circuit examples under 2P. No matter which way current flows in those examples, one of the two tied breakers will trip under proper polarity because polarity is opposite between each pole, and that will break the arc.
I've previously helped walk a few folks offline through setting up Flooded Lead-Acid batteries with their chargers and inverters to get the most possible functionality out of them. Although FLA is deservedly falling from favor and deployment, there will always be a small use-case for them as...
Is stepping up or down a single output voltage with a transformer an option? You're talking about using two power stations but maybe it would be easier to have a single larger one with an external transformer for specific loads. You can get a 5000W unit for less than $100.
Ahh, understood. So you're not using the MPPT or the DC-to-AC inverting capabilities of the DY220SL-001, it's converting single phase to three-phase for the submersible like I thought could be the case.
750 Watts is about right for a 1HP AC induction motor mechanical output rating, but that...
You can combine multiple series strings into a Schneider MPPT's single input. This is exactly what I'm doing with all four of my MPPT 60-150 controllers, each with 6 strings of 3 panels. Every string needs a blocking diode installed inline or the MPPT functions won't work right. Inline diodes...
I've run MPPT 60-150's since Xantrex came out with them back in the day. Until earlier this year I had three of them connected to a 12v nominal battery bank. The first array was configured to 24v nominal, the second for 48v nominal, and the third for 72v nominal. My observation with these is...
Seeing as that was your first post, welcome aboard.
If you're doing just grid-tie you'll need either a string inverter or micro-inverters.
Either option will have input specifications for the solar panel voltage and current minimums and maximums. You can post back with the specifications on...
I have a pair of XW Pro 6848 in sync with the whole house on their load side.
The desire is to power the loads with prioritized available DC, and use the grid to make up the difference when batteries fall below Grid-Support voltage.
It is desired to have zero draw from the grid (AC1) when DC is...
If you're looking for heat you might pick up a big hot water solar collector, build a simple circulation system with an ethyl/glycol solution run by a small 12v pump. Some of these pumps are built to run directly from a very small PV panel with a wide voltage range. Inside, an automotive...
I can't imagine living in the path of hurricanes, kudos to your self-sufficiency.
With what you've already got, I'd probably use the generator only to charge batteries, and then run from the batteries. That also gives you the option of minimizing the annoyance of the loud AF generator while...
Here's an old post that came up for me in "Similar Threads".
Did you get this sorted out?
Before I saw this was from back in February I was going to ask about the role of your batteries in your setup - whether for backup, or cycling daily with PV production and self-consumption, etc.
Based on your posted data:
Voc = 49V x 11 = 539V which is less than the 550V limit - good.
Vmp = 46V x 11 = 506V which is less than the 510V limit - good.
Calculated the Imp to be 12.5A which is less than the 29A limit - good.
Isc is probably around 13.4A is plenty safe for the 35A limit - good...
If your MPPT displays input voltage, a telltale sign it's throttling back is that the PV input voltage will begin rise past n*Vmp. So, for example, a 2S string of 24V-nominal panels with a Vmp of 37V will be around 74V at peak MPPT. The way MPPT controllers throttle back is by allowing the PV...
Lead chemistries can only be discharge to 50% without risking sulphating the plates or grids. Derate the kW/hr. capacity by 50% and use that for sizing. The other issue with lead is voltage droop under load heavy load. Voltage droop increases as state of charge decreases. Running the...
