This situation can cause flicker, although would think that with the SWs running as chargers only (ie AC power not passed through from the genset) that there would be less flicker than when using only inverter/chargers alone.Īnd, it is quite possible that hardwired smoke detectors may well have very cheezy power supplies, that may not behave well with Alt energy power under all conditions - just guessing. This may not apply to your particular situation. My Honda EU6500isa is unable to tolerate this when the SW+es are in Absorb - this energy dump drags one side of the AV line input from the genset out of regulation, and is dropped by that one SW+, and will cycle like that until I stop the charge, or back off the charge current to some uselessly small amount. When in Absorb, have read that these venerable Trace/Xantrex SW/SW+ inverter-chargers will dump some battery energy back into the AC input source (like your genset), as a voltage/current regulation method or artifact of being bidirectional. This asynchronous current drawn from the 240 VAC input can really disturb some voltage regulators on gensets, especially in Absorb. While these units do stack, stacking seems to only sync the sine wave of each, but each charger seems to be independent, especially when regulating voltage - as in Absorb and EQ. When Vabs is reached, current sharing is less equal, especially as Absorb progresses. Can run more than 175 A charge rates in Bulk. In Absorb, and even EQ, the battery impedance is higher, so voltage ripple might be higher, although then, the charge current is lower, as well. Doubt that there is much voltage ripple during heavy charging in Bulk. The problem is to individually cable each inverter and to connect them at opposite “corners” of the batteryĬan anybody explain how I would cable 2 inverters to opposite corners of the same battery? Art work is always good!Ī number of folks seem to complain about flicker with OB Inverters - have no experience with them, though.įluorescent lights are quite prone flicker, at least the long-tube varieties. Rate and/or the smaller the battery, the more pronounced this problem would be.

This causes the chargers to not reach their full output - two battery chargers on the sameīattery may not provide twice the charging rate to fill the battery in half the time. The most significant problem with multiple inverters charging the same battery is the voltage ripple caused I then tried just the master and it seemed to put out almost as much as the slave but neither put out what I have them set at. On the SW5548's I took off the synch cable and the master still backed off some. The flicker went right through and it pulled the input voltage down bad. I tried running the Outbacks through the transformer as I'm doing with the SW5548's and nothing good happened, but nothing real bad either, it didn't like it though. Used to play with hit-or-miss back in the day and a 1920 Stanley, that was real fun, the Tesla of the time. Turning off the smoke alarms during charging was easier on me than backing way off and listening to the gen run longer. Would the transformer do away with the "weird stuff" from the Outback/gen interaction?Īlso I tried backing off on the charge rate by a few amps per inverter with no real change. boB can explain it better than I can but if you back the charge current down some it will help a lot." They do some really weird stuff to the wave form on generators with electronic voltage regulation. What would that do if I put it in between the gen and the Outbacks? I put a Hevi-Duty shielded general purpose transformer model #S5H15S in between the gen and the new to me SW5548's for leg balancing, works great. Also I have searched and posted, on the Outback forum, about the flicker thing in the past and haven't found anything, so if this works it might help somebody else. Sorry to bump my own old thread but the project mentioned in my thread "fun and games off grid" has brought up a new question about this thread.
