Uncommon sense?

Keep your wiring tidy and organized. If you are looking to keep your homeowners insurance, get the wiring inspected when it is in your home or office space. When this wiring is installed in a summer cottage, backwoods cabin, RV, etc- even though it may not be inspected: do the work to a quality level where if it were to be inspected- that it would pass. This is mainly a safety issue. Continue reading

Xantex Autopsy Finale.

While I had hoped to have all the problem units functional, that is not to be at this time. If I should find someone who has the solution for the over voltage fault (when none actually exists in the circuit) I will link to that post in the future. Continue reading

Further Data on the Xantrex Autopsy

Seems a shame that people just give up on these older inverters when something small like a thermistor fails. Seems those that only promote replacement are made of money and likely will never read this blog. Their loss. But why replace an inverter when the failed part is about 3 dollars US? Or less….

Simple and Small 1 Amp Gel Cell Charger Circuit

The circuit in the image has some additional notes. It can be adapted to other small battery types by raising or lowering the charge potential via changing the resistance value Continue reading

The Xantrex Autopsy part 1.

Now, why would someone buy one of these units used for 250 dollars on up used? Simple- These units are built for long term service and 100% duty cycle. Sure, you can get some cheaper “Class D” type inverters, but those are far more noisy in radiated RF, and while cheap- they are not all that durable- one short on the output and most are finished. They lack serious protection of the unit in use- the Trace made units are the better choice. Continue reading

Inverters 101, including the RF aspects no one has discussed before.

But what has not been discussed thus far is the Radio Frequency noise aspect of some of these circuits, and also some commercial solar controllers can and do radiate RF as a byproduct of the ability to eek a little more charging time from a rising and setting sun. Continue reading

A Little More about Automotive Alternators…

You do want to have the adjustability so you can fine tune the system so it is not trying to charge at full output at all times- unlike a car or truck, it does not need to go to full charging rate. A moderate rate of 20 Amps will recharge quite effectively, as will 10 Amps. Continue reading

Using Zeners

If you are serious about trying to use Zeners I will direct you to the various factory handbooks for additional information about their uses. The use of Zeners in alternative energy circuits in general is rather limited though, and they really require isolation to limit their load on the circuit which can be dissipating energy you may want for your battery. In other circuit applications outside of the alternative energy systems; they have their uses, Continue reading

quick update

…;Since the last posting I have recieved from a friend, several large inverters/charge controlers that must be checked over prior to selling them. Among them is Blue Sky Solar Charge Controller which is likely the first of the items to be covered…. Continue reading

A Minor Update to the Regulators

I will also be posting a simplified 10 Amp Regulator circuit in a couple days, it will handle more than 10 Amps, and it omits the 2N3055 Continue reading
