Opening the switch isolates the grid so house only is on draw.

Switched on the bypass on My inverter and all was ok. What did i did I bypass my batterries or the grid or did i switch from the top 5 batteries tp tje bottom 5 batterries thanks in advance

The said reason being to protect any utility workers from getting zapped by my electricity traveling back through the power grid. Makes sense to me, but is there any way to safely bypass this "feature?" IE the grid goes down but we can still use the watts we generate. I'm open to solutions that include batteries, but curious if there is a way to do it without them.

Load testing with an load test instrument is probably best, but if you get good backup time, use it for a season or until it limps.
Teresa Duran wrote:Thanks - I checked there is voltage coming from the batteries / or the batteries are pushing some power but not enough to power it all. I am a true greenhorn/novice so I guess I need to get to doing some more learning about this. I leave out in the country so I might need to call a tech but I am always worried about who I will get cause I am so far out in the backwoods
Teresa Duran wrote:so here is an update - I was able to get the system back on line and all was fine - after cycling it and restarting everything - however, it runs for sometime and then the inverter shuts down and gives an overload red light.
If you two don't stop this rough-housing somebody is going to end up crying. Sit down and read this tiny ad:
