I've seen solar panels exceed their Voc (open circuit voltage) rating and generate more than rated wattage after rain storms clear the air. During one incident, it went high enough to damage a small (250 watt) grid tie inverter, but other equipment was not damaged.

This problem is extremely rare and likely caused by improper mixing of the foam components.

For example, California has waived asset tests for SNAP: 1. Which households are subject to the Resource Limit? Resources are counted only for those households that : 1.Contain a member who has been disqualified from participating in CalFresh because of an Intentional Program Violation...

It's not just mothers with kids, anyone with sufficiently low income (below 2x federal poverty level) can qualify for SNAP benefits.  And most states have waived assets tests in recent years.

If your income is low enough to qualify for SSI, you should also qualify for snap (food stamps) and free lifeline cell phone or landline service (and discounted high speed internet from some providers). In most states, snap eligibility is solely based on income and there is no longer any asset test.

If the insurance coverage is from the owner's own collision coverage, it will usually be limited to the blue book value of the vehicles which would be very low for older vehicles.  Is this also how it works for trailers and campers?  I had a comprehensive claim after hitting a rock that slid...

The current from the starting battery into a depleted battery is limited by wiring resistance and by the relatively small voltage differential between the 2 batteries. A fully charged battery might be 12.6V or so and the depleted battery might be at 11.5V so the voltage difference is small...

You could add a time delay relay or a voltage threshold detector which would only close the relay if the voltage was high enough (13-14V) to confirm the engine was running.    I prefer running a higher voltage house battery (24V or 48V) and using a DC-DC converter to charge it from the vehicle...

On the other hand, this doesn't need to be so complicated or expensive. One wants the deep cycle batteries to be connected (in parallel) with the engine starting battery when the engine is running, but otherwise disconnected. This function could be achieved with a simple relay controlled by...

Disconnecting the battery while being charged by the alternator causes a large voltage spike from "load dump": https://en.wikipedia.org/wiki/Load_dump In general, I prefer battery isolators that use latching relays because a latching relay only consumes energy when switching states. Unlike a...

Have considered closed cell sprayed urethane foam? That provides twice the insulation value per inch compared to fiberglass. It should also function as a vapor barrier.

Looking at the total amp-hour yield over the cycle life of the battery provides some insight. The 24V Telecel brand LiFePo4 batteries I use have this cycle life rating. For simplicity, the calculations for ah over lifetime below are for a 1 amp-hour rated battery. These calculations assume...

Solar cyclic use means charging ends when the solar panels are not longer in full sun so that is very different than when they are float charged continuously such as for backup use. In solar cyclic use, batteries would only be full charged (or overcharged) for a short time. The cycle life of...

LiFePo4 is much more tolerant of excessive charging voltage than other lithium chemistries.  I'm not aware of any data that suggests cycle life or capacity will be reduced by slightly elevated charging voltage, especially in solar cyclic use when the charging voltage will not be sustained for...

The nice thing is one can qualify even with income of up to 26K/year in some states including California. Keep in mind that there are now numerous cell phone providers offering lifeline cell service and the plans they offer vary a lot. In California, the better ones will provide a free android...

Ideal max charging voltage for LiFePo4 cells is 3.65V, but this chemistry is tolerant of mild over voltage, to a max of 4.2V per cell. Under typical solar charging conditions, you can set set the max voltage to 16V (assuming a a 4 cell LiFePo4 battery and battery management device that prevents...

The 24V Telecel brand LiFePo4 batteries I use have this cycle life rating 80% depth-of-discharge, 2000 cycles 70% depth-of-discharge, 3000 cycles 25% depth-of-discharge, 8000 cycles The Telecel batteries include battery management electronics so can be used more-or-less as drop in replacements...

Most states have waived assets tests for snap/food stamp eligibility.  So, eligibility is based solely on income and one can still qualify with any amount of assets.
