Sun Pack (Hybrid Home UPS)

SUN PACK is a solar hybrid inverter which utilizes both the Solar power and Grid power to charge the batteries. Solar power is of the first priority while charging. This means that when Solar power is available, the batteries will be charged with it only, irrespective of whether Grid power is available or not. It is designed to give you the maximum advantages from the Sun and thereby reduces your Electricity costs.


SUN PACK is very easy to install. It fits your budget and also helps to cut your electricity costs. So, it is double advantage to the user!! Unlike other sources of energy, SUN PACK and the Solar Panel do not emit harmful gases and residue. Thus, it helps in keeping the environment clean and healthy.

    Sine Wave Output

    Prevent crashes in computers, weird print outs and glitches in monitors with clean/distortion free sine wave output from UTL’s SUN PACK. Now run inductive appliances in a much quieter and cooler way, in  the same way as these appliances run on utility supplied electricity [Top]

    Preference to Solar Power over Grid power

    SUN PACK gives first priority to Solar power over Grid power during charging. It means that when Solar power is available, the batteries will be charged through Solar Power whether Grid Power is available or not. It goes to Grid power only when Solar Power is unavailable.Thus it helps in reducing electricity costs alongwith keeping the environment clean.

    Can operate without Solar Panel also

    SUN PACK can be operated with or without Solar Panel. The user can use SUN PACK as a regular inverter without bothering about use of solar power. Whenever the user feels that solar power would be beneficial, he/she has to just install a Solar Panel and then derive the benefits of Solar Power.

    Any battery option

    SUN PACK from the house of UTL has the intelligent feature to recognize the type of battery connected to it. May it be an ordinary battery or a branded one, a tubular battery or a sealed one. No matter what the type, it auto adjusts the battery’s charging characteristics accordingly. Even those batteries which cease to go over 13.5V after a while of use work flawlessly with UTL’s SUNPACK.

    Extensive electronic protections

    There are a number of protections that the SUN PACK ensures. It stops reverse current flow from battery to solar array, it provides load short circuit protection, it provides Battery/Panel reverse protection through DC fuse and Overload protection also. [Top]

    Affordable and easy to install

    SUN PACK is extremely easy to install and is available at a very low budget. It also helps in reducing the electricity costs. This means double advantage for the customer. Thus, it is an ideal product for present day and age.

    Battery Health For Longer Life

    The SUN PACK feeds the battery installed to it a constant boost charging current until its voltage reaches 14.2V and the float current (which is very close to zero) then maintains this voltage above 13V. Thus reducing the float current ( flowing for the longest period during the entire process) to zero, ultimately resulting in much enhanced battery life keeping it fully charged simultaneously. [Top]
