As most of us understand that the outdated resources for electricity generation are the major culprits for slowly changing and eventually killing our planet. Voices can be heard from oil producing or coal mining camps that are outright in denial, claiming that renewables are not green technologies. I am not disputing that whatever generators are…

There is the potential for massive failure of an entire battery bank when certain conditions meet. One of my customers lost an entire battery bank of 16 X S6-460 AGM batteries due to a combination of issues. The issues that lead to this failure were threefold and are not listed by importance to each other,…

There are pros and cons for both, roof, and ground mounted PV modules. ROOF MOUNT PROS: Depending on the distance to shade creating objects it may be advantageous to mount PV modules (Solar panels) on the roof of a building as you are naturally gaining height for better sun exposure. In most cases the roof…

To all of you living off grid. Yes, this grant is for you as well. Upgrade your PV array and get up to $ 5000 plus an additional $ 600 for the pre and post audits. See below. Here is the lik to the NRCAN website to create your application https://www.nrcan.gc.ca/energy-efficiency/homes/canada-greener-homes-grant/23441?utm_campaign=eccc-eccc-ourenvironmentsem-22-23&utm_medium=sem&utm_source=ggl&utm_content=ad-text-en&utm_term=greener%20homes%20grant&adv=2223-243400&id_campaign=16978261620&id_source=135321591509&id_content=593938646599&gclid=Cj0KCQjw37iTBhCWARIsACBt1IxxaJl7PaXpie0FccuxaTJnnfPyGN-i1ZO0CyMdF-pKB14wmMx94kAaAmbNEALw_wcB&gclsrc=aw.ds

Here is another high end LIFEPO battery that has all necessary certifications to be used in residential applications. Developed with our own LFP (lithium iron phosphate) cell to ensure the highest safety Self-designed BMS protects the cell in all angels such as abnormal temperature, current,voltage, SoC, SoH Vertical industry integration ensures more than 6000 cycles…

To all of you who are in the market to purchase electrical off grid components, please talk to someone who knows what is required to provide you with a well functioning, safe and expandabe system. The so called “Complete System Kits” are most often incomplete. The most common shortcomings are: Undersized or oversized PV arrays…

This is awesome, you can actually apply for energy efficiency grants form the Canadian Federal Government and also from the Enbridge program as well as long it is your primary residence. Easy access, easy process and for us Off Gridders, less generator time.

Corrective Equalization & Instructions  The frequency of corrective equalizations will vary by system due to factors such as operating temperature, frequency of cycling and depth of discharge. Loss of capacity, imbalance and low specific gravity readings are indicators. Running frequent equalizations on batteries that do not require balancing or desulfation will overcharge and deteriorate the…

In my opinion, the Sol Ark inverters are currently the best North American made all in one inverters. They include everything an Off Gridder can wish for: Features include: Two Built-In 500V Charge Controllers 1 – 4 PV Strings Battery Disconnect 48V Battery Input Auto-Generator Start Rapid Shutdown Signal Built in Arc Fault and Ground…

EQUALIZATION: Individual cell readings will vary slightly in specific gravity after a charging cycle. Equalization, or a “controlled overcharge”, is required to bring each battery plate to a fully charged condition. This reduces stratification and buildup of sulphation on the plates; two circumstances that shorten battery life. One of the most commonly asked questions is…
