Pure Sine Power Inverter 2KW - AIMS Power

AIMS Pure Sine Wave Power Inverters provide reliable transformation of DC power from a battery into AC power that can then be used to run lights computers, printers and even medical equipment.

2000 Watt Pure Sine Power Inverter

This is an industrial-grade unit with the ability to withstand surges of up to 6000 watts for 20 seconds, and  it achieves this by virtue of its direct connect terminal block. This feature is one of the more sought-after in the inverter industry, allowing users to surpass the 1,500 watt maximum output of a GFCI outlet that would typically be seen on an inverter.

2000 Watt Pure Sine Power Inverter

The 2000 watt 48 volt low frequency AIMS Power inverter charger transforms DC (direct current) power, produced by solar panels and stored by batteries, into AC (alternating current) electricity that can be used to run most all tools and appliances. This inverter also has a built in AC-to-DC battery converter charger, which allows users to recharge their battery bank from an AC source such as a fuel-powered generator, shore power or a regular outlet at home.

Battery Boost Circuits

(This is a thread of my Google Talk many years ago - you will be able to notice text communication is quite difficult. sometimes even verbal expression will not specify the need, We need clear drawings and specs)

Sam: I was going thrugh some IC like MAX8880/MAX8881, can u help me with using that with input from my batteries?

dapj: let me see

Sam: It's datasheet says that Supply current [Iin] = 10uA max does it mean it will draw a max of 10uA from my battery?

dapj: it looks like it will work from 2.5 to 12V and it can give you a 5v out 200ma

Sam: Exactly!

dapj: is 5V enough 200mA too, but it cannot boost voltage

Sam: my concern is with my input. What about using rechargeable batteries [4x1, 2100mAh] to act as input to this IC. will it consume 10uA if I do so while my load to the output may vary from 100mA to 200uA

Battery Boost Circuits Max8880

dapj: if you want 5V you need to feed this atleast 5.5V this chip does not consume anything (the uA is Standby consumption )but it is not a voltage doublet or a charge pump

Step-Up/Step-Down Converter Features Ultra-Low Quiescent Current

Sam: OK, I need to feed it anything between 5.5 -12V, Do we get recharge battery near about 2V, 2100mA

dapj - a 12 v battery can be recharged when 11.8V is reached it may charge upto 12.8 V in Li ion

Fast, smart NiCD/NiMh battery charger - The MAX713 is designed for NiCd batteries, while the 712 is for NiMh batteries.
