Hi. I'm not a electrical person but need assistance. Since I had a Luxpower Xlp installed, we are having earth leakage tripping 5am on a weekend. All earth bonding were checked, rewired and again. Problem not solved. The inverter firmware was up dated, Cfe battery was checked. Problem still excists. About once a week (Sunday/Monday) at early morning while the system runs from the battery the EL trips. It is mentioned to me that Luxpower is discontinued? Any thruth of this rumor? Any suggestions is appreciated.
