iHHC2 - hand held controller for Hillstone AC load bank control


The NEW iHCC-2 from Hillstone is a robust intelligent loadbank controller, that allows common connection of multiple load banks.


The controller allows "on the fly" setting and selection of the required load. 

The load can be quickly set from 0 to max load via 3 robust push buttons: x1 x10 x100.

The operator can also make fine adjustment in 1kw steps in real time via up down increment and decrement buttons.


The iHHC-2 allows for parallel control of up to 8 load banks. 

When multiple load banks are connected in a daisy chain loop, the single controller will control all the load banks.

Feature Upon initial start up of the load bank the display on the controller of the maximum available kw.

Feature THe NEW iHHC-2 uses a 4 line LCD display with high illumination showing 4 digit KW readings.

Feature The LCD supports an 270o viewing angle and allows viewing even in bright sunlight.

Feature The NEW iHHC-2 is compatible with the the 2 types of AC loadbanks models in the product range.

(i)     The standard loadbank displays the default load values at 415V to always be displayed


(ii)     The enhanced real time load display on the iHHC2 incorporates panel mounted power meter fitted to the load bank.  This display the actual load values on the generator or UPS system on the iHHC2.

Existing Customers hand held upgrades

For customers that have the old iHHC controller we can offer an low cost hardware upgrade to the new iHHC2.

We only require customers to supply the M36 serial number of the purchased load bank and we will arrange collection and replacement.

Understanding generator wet stacking problems

Part One from our series of informative load bank usage blogs

Regular load bank testing of your generator prevents damage or engine failure that can occur from running under load or below the WET STACKING LEVEL

Wet stacking - the problem:

Wet stacking occurs due to running the genset on a low load.  This in turn prevents the engine temperature running at the required design temperature, typically 100 - 200oC, and results with un-burnt fuel deposits being left and building up in the engine cylinders. 

This fuel build up will over time line the combustion chamber cylinders and cause a reduction in the engine ratings and efficiency, which will ultimately cause premature failure of the generator.

Wet stacking - the solution:

Running the generator on load of 30% - 100% of the genset rating will allow the engine to reach the recommend operating temperature.  This will burn off the choke deposits and discharge lots of black smoke and maybe hot balls of carbon out of the exhaust.

Load banks can be used in two applications to prevent wet stacking, these are:

      (i)     100% load bank testing
As part of regular maintenance and after say running the load bank for 100 hours at low load the load bank testing for between 2 to 4 hours will be sufficient to clear the carbon deposits and prove the generator efficiency.

     (ii)     Installing a permanent load bank with auto load shedding.
A special controller is fitted to the load bank and the generator output to monitor and regulate the load to  ensure a minimum 30% load setting is always applied.
