Noma 1800w Backup Power System Manual

by

Canon mf 3010 service manual. Hi there, thanks for the great advice in these forums. I'm hoping to find a bit of specific advice on a Noma-branded Xantrex Powersource 1800 battery backup. It's an old unit, with maybe 10yrs service as a sump pump backup, so the batteries inside are not holding a charge anymore, but it does still supply non-sine AC power when connected with booster cables to a running automobile's red battery terminal and engine block. It is rated 1800W continuous and 3600W peak, but it is cutting out with an overload error (E03) with even just a 900W space heater or 1/2hp water jet pump plugged in by itself.

None of the components on the circuit board seem to show any signs of physical damage or burn marks, and all eight 30amp fuses look ok. It might possibly have received a shock when a tree in the backyard was hit by lightning while it was in the basement, unsure on that. Here are a few pics of the setup and circuit board. There are reports online of this Powersource unit having transformer problems. Can these components be DIY repaired or otherwise jury rigged for a quick fix?

Computer backup power

Nov 30, 2010 - I have had a Power Source 1800 for about 3-4 years. I use it to backup my sump pump. Other than for testing, the unit has never needed to.

I only have a basic digital multimeter for testing, and am learning as I go what can be tested for what. Thanks for any advice that will get this unit running strongly again, it'd be great if it could power the oil furnace too! Quote: E03 Overload shutdown while supplying backup power. The AC product(s) connected are consuming more than PowerSource 1800’s power rating.

Use products with a total power consumption within PowerSource 1800’s continuous power rating of 1440 W. The AC products connected have a surge power that exceeds PowerSource 1800 surge capability. Use products with a total starting surge power within PowerSource 1800’s capability of 2880 W. One or more of the connected products are damaged.

Have the damaged product serviced by a qualified technician. Get those dead batteries out of it and recycle them down at the port I believe that the poor contacts and small diameter wires you are connecting to your 12VDC source are insufficient for your load. You need some heavy cabling for this, heavy and short as possible with solid contacts For a 900W load you would be pulling 75A at 12V f the inverter were 100% efficient, which it is not. Probably need closer to 100A.your toy jumper cables just aren't going to do that mate. And that is assuming that your vehicle alternator can make that, which I doubt. If you look at the spec sheet: Internal battery capacity 51 amp-hours (3 × 17 amp-hour batteries) Internal battery voltage 12 VDC (nominal) It uses three 12V batteries rated at 17AH each for total of 51AH (connected in parallel). So per spec sheet it can continuously put out 120V @12A = 1440 Watts.

So we have 12VDC to power the inverter circuit to create 1440W of power, for the sake of calculation we make it 100% conversion efficiency (which cannot be) that means the current draw from the batteries 120A! (12V x 120A = 1440 WATTS). Can it actually do that? I do not see run time rating at full load.

It shows Microwave 920W for 12 minutes.

Xantrex XPower PowerSource 1800 If you've ever had to deal with the inconvenience or a power outage, whether in your home, at the cottage, in the office, or in your workshop, you'll appreciate the benefits to be had from an emergency power backup supply. Generators are the way to go for longer term power backup - particularly for anyone living in remote areas, or during winter months when blackouts can last for days at a time. However, when you need power backup for a short period of time, battery backup power might be a better choice. Generators are more expensive than battery systems and they typically require a combustible fuel such as gas, diesel, or propane, making them noisy, and producing harmful emissions. Usually they need to be operated outdoors. If you live in a condo or apartment they're out of the question. Battery power backup systems, on the other hand, are silent in operation, emission free, maintenance free, and considerably less expensive than generators.
