We're from Australia the land down under so our standard is AS/NZS 60898 but we're not even allowed to read them unless we pay.
See if Carling or other breakers comply with your standard and are 13 mm. Just a few of those would free the space for a baker's dozen.
I've switched from Square-D QO to Schneider Multi-9 to Midnight/CBI or Carling magnetic-hydraulic for performance reasons in a couple portions of my system (all the rest is QO).
Midnight/CBI can be operated continuously at 100% of rating, and Carling at 95%, due to where there "must not trip" values are set, and they are unaffected by heat so no 20% derating like thermal breakers.
Never seen anything skinnier than the standard 18mm units in an Australian main circuit board.Seems to me those breakers are the fat variety.
DIN breakers and fuses come in at least two widths, so for smaller wattage you should be able to fit more.
Ah, the DC breaker. Yeah that was a kit, breaker + housing. ZJ Beny. I got mine from SBP Electrical but can get them from a few places, e.g.:MCCB is the breaker under your off-grid inverter for the battery disconnect. They are the next step up of Circuit breakers.
Not common here. I have one for the small off-grid solar PV array but that's it.Maybe I missed it but your electian didn't put any SPD in when you got your boards installed?
It's not clear to me why the inverter creates this deformation in the AC waveform when passing through grid power (yet produces a decent waveform when operating from the battery).
UPS mode.Are you using APL or UPS mode? APL seems to just passthrough grid, but when I turned on UPS mode I could hear relays clicking and it seemed like it it was regulating the voltage to exactly 230V output where as APL was just following the grid voltage swings.
Love to see what you find out.UPS mode.
Interesting, I hadn't thought of testing that setting. Even so it just passes through the grid's voltage. It's easy to see as my grid voltage is typically 10-12 V higher than standard and the inverter's own output. I don't hear any clicking. Hard to hear much over the noise of the fans!
I will make the setting change at the next opportune time and report back. Thanks for the idea!
