  • Catalytic Caps to Reduce Battery Watering

    About two months ago I did the overdue spring servicing of my cottage batteries. I have a 10 year old 24V bank of 2V cells with 20kWh of capacity. These are recharged by 800W of solar, and I added 1.5kW this spring just for the fun of it – solar panels are so cheap now.

  • Designing Industrial Solar Systems for Dual Voltage Loads

    Many industrial solar system designers are faced with the issue of power systems needing to supply both 12 and 24V loads. Though SCADA systems are available with either voltage, issues arise when equipment of differing DC voltages is incorporated into the same system, for example 12V radios and 24V sensors. The solution includes the addition of a DC-DC converter (available in a variety of ampacities) to make all of the loads the same voltage to match the battery system voltage. Continue reading

  • Industrial Solar System Sizing Guide - Industrial Solar 101

    HES has provided equipment for thousands of Industrial Solar Power Systems operating in Canada. The key to repeat business is a solar power system that always works. A successful solar power system is one where the potential solar production always exceeds the power needed by the equipment, the batteries stay more or less fully charged, and where there are no interruptions in power delivery.

  • Deep Cycle Battery Maintenance Part 1: Assessing Water Levels

    Knowing how to check deep cycle battery water levels is an important step in battery maintenance.

    More battery banks are lost due to poor maintenance than any other cause. Regular maintenance should take place every three months, and checking and maintaining deep cycle battery water levels is an important step in that process. Continue reading

  • Deep Cycle Battery Maintenance Part 2: Checking Specific Gravity

    In this article, we'll show you how to check the charge of your deep cycle battery using a Hydrometer.

    More battery banks are lost due to poor maintenance than any other cause. Regular maintenance should take place every three months, and ensuring your battery's charge level is full is an important step in that process.
    To ensure your deep cycle battery is fully charged you'll need to measure the specific gravity with a Hydrometer or Refractometer.

  • Deep Cycle Battery Maintenance Part 3: Checking Battery Voltage

    In this article we'll show you how to use a voltmeter to check your battery's charge level.

    More battery banks are lost due to poor maintenance than any other cause. Regular maintenance should take place every three months, and ensuring that your battery's charge level is full is integral to that process. You can use a voltmeter to quickly check the charge level of your deep cycle battery. To do this we first need to check the Open Circuit Voltage. Continue reading

  • Solar Battery Banks & the Off-Grid Cabin or Cottage

    The most important part of choosing a solar battery bank is gathering load profile information from the customer.

    If possible try to forecast any foreseeable loads that may be added in the future as well. If the solar battery bank is not sized around the load profile the system will not be balanced.  An unbalanced system will require greater generator run time in order to avoid battery failure. Adding new batteries to an old battery bank and ‘expanding it’ is not a good solution.  When new batteries are added to old battery banks, the new batteries will only be charged to what the old batteries can handle. This will reduce the effectiveness and lifespan of the new batteries, and will cause further trouble shooting expenses. Time spent developing a load profile will avoid these kind of headaches down the road.
