A:AnswerI have a backup generator also. I try to keep the UPS load
at around 50 to 75% of its rating under normal operation. This has given me enough time for my generator to kick in when needed.
A:AnswerGreetings. Thank you so much for considering our Backups 900 VA like BVN900M1 or BE900G3. (https://www.apc.com/us/en/product-subcategory/88975-home-office-electronics/?N=brand%3Dapc%26country-code%3DUS%26language-code%3Den%26subcategory-id%3D88975%26pageParam%3DsubcategoryListing%26filter%3D%26ats_rated_power_in_va%5B%5D%3D900%25C2%25A0VA&selected-node-id=88975). If your intention is to protect your non server type computer(not high power consumption) or router/modem for internet against surges and expect battery backup during power outages and the output power capacity of those loads will not exceed the limit of the specific backups unit then you can consider using such back ups model even for television. However, its a NO for refrigerator because our ups units are designed for IT devices only. Thanks and have a great day.
A:AnswerThank you for your inquiry. I am sorry to hear that you are having problems with our unit. it could be the battery but generally when they fail the replace battery light will light on them. The internal batteries last around 3 to 5 years so it may be at it's end of its life. If it isn't the battery it could be there is power issues in the night because the clicking can mean that the UPS is going on and off battery.

A:AnswerThank you for your interest in our products. Unfortunately we really wouldn't have an UPS that would work with a tankless water heater. There is a chance that the UPS could become overload and you wouldn't want our units to be installed in an area that has moisture. The BVN900M1 would support 480 watts of equipment connected to it so there is a chance that the water heater would overload the UPS as well.
A:AnswerI am not an electrician, but would recommend you get professional advise from an electrician. Having said that, I would guess your sewing machine has a polarized (two-prong) plug which means it is designed to protect you sewing machine powered from normal household power. Adding a surge protector helps protect equipment when power flickers.
A:AnswerThank you for your interest in our products. Unfortunately our BackUPS require a ground connection. There wouldn't be a way to turn off the alarm on the unit. The alarm is there because if the UPS can't ground any excessive current can be shunted to ground.
A:AnswerThank you for your interest in our products. The BVN900M1 would provide 1 hours and 7 minutes of runtime with 60 watts of equipment attached to it.
