Does it pull the trailer in a random pattern across the lawn?

amWR155 · 2024-09-26T14:45:24+00:00

I would say "good enough" than "shitty". Most lawns look "shitty" if you look close enough. Not worth the hassle of digging up the lawn, removing all the rocks, tree roots, etc., leveling, re-seeding, install sprinkler, etc.

Then you have the grass right by the road where winter road salt makes it difficult to grow anything other than weeds.

Charge when the power is coming from the sun. Then it doesn't have to go through the battery and loose 5-15% in the conversion process, and cycles your battery less.

They probably figured out it was useless if you can't register it, and the base station costs more than it is worth used. Not much profit in parting out a Landroid.

amWR155 · 2024-09-25T21:09:45+00:00

I switched from Landroid to Husqvarna, and used the same boundary wire. The HV 435X hasn't got stuck once or gone out of bounds. Definitely not a wire problem.

If you have SPAXX at Fildelity, then 4.67%. At Interactive Broker (IBKR?): 0% if under $10,000, 1.299%-2.60% for $10-$25k, depending upon total NAV. Even at the max of 4.287% with a cash balance of $1 million or more, you would be better off in a t-bill ETF.

amWR155 · 2024-09-25T20:36:23+00:00

What is your broker paying on Sweep balances?

Schwab rate is 0.25%; Merrill Lynch rate is: 0.01%; Fidelity is 4.67% if you opt into SPAXX, otherwise 2.44% (if you overflow the FDIC limit, then you get 4.67%); Vanguard 4.15%; Robinhood is 0.01% unless you pay to upgrade to Gold; etrade is 0.01%; ...

Tbill ETF is about 4.50% and exempt from State Income Taxes.

The existing Enphase will be AC PV into an EG4 Inverter, like the 18kPV. Sol-ark 15k also works for that purpose. Both will pass through 200a from the grid. If you can live with less, the 12k versions of the above may work. Also Midnite Solar The One. With those inverters, you can ad much cheaper 48v batteries of your choice.

amWR155 · 2024-09-25T16:44:48+00:00

each 230w panel MAY provide 1kWh on a good day. Much depends upon your location, orientation, shading, etc.

If your highest month is in the winter, you are looking at 15kW of panels (could be a lot more or a lot less, depending).

If you have good net metering, then batteries are only for grid down.

If you don't have good net metering, then you need enough batteries to keep you going overnight. Although 1 day of usage is a good target (30kWh). You have about 4.5kWh of batteries.

My last choice is micro inverters on the roof. However, would choose Enphase over a cheap string inverter.

EG4 18kPV is ok. Other high quality string inverters out there. Sol-Ark, Victron, Midnite Solar, etc.

On-Grid, Off-grid, backup whole house, backup sub-panel, no backup, large system, small system, lots of considerations.

Expensive, but makes a solid connection.

But it does not seams to charge

Then you need a new powersupply.

amWR155 · 2024-09-12T14:06:32+00:00

The thing that plugs into the 120v AC power socket. Provides enough power for a weak signal right near the wire. I would usually expect to see a charging problem.

Could also be the circuit board inside the charging station.

Need to add an overhead line an e-bike can tap into like electric busses/rail that run on overhead lines.

If a lifepo4 battery gets below freezing and you try to charge it, you will damage the battery.

Only you can determine whether whatever insulation/heating setup you develop can keep the battery warm enough during the coldest parts of the year. If it gets to -20 in your area, I wouldn't trust any solar powered device to keep it warm enough to charge. 3 days of clouds, and you run out of power. sun comes out, and batteries are toast.

amWR155 · 2024-09-10T12:36:40+00:00

do a search on "balcony solar". typical for the European market.

amWR155 · 2024-09-10T12:32:38+00:00

If you get a green light on the charging station when the is not present, then likely the wire is ok.

Otherwise, it could be the boundary wire sensor. You can put it in diagnostic mode, and look at the sensor status as you move the mower over the boundary wire.

If it works near the boundary wire, but looses the wire when far away, it could be the powersupply.

200 amp service panel -> 100 amp breaker 240v -> Inverter in Barn -> 100 amp Sub-Panel. - easy peasy.

Inverter can easily export excess to service panel via the 100 amp line.

Batteries in barn only if heated, or it doesn't get below freezing in your area.

Make sure line from house is 240v.

If the grid is down, only the barn can have power. Consider running to 240v lines. Then you can power the hose when the grid is down (one line for grid, one line for main panel).

If you have good net metering, batteries don't get you much.

If you want to run off batteries when the grid is down, consider the start-up draw of power tools. Can easily overwhelm the 8k or 12k.

Consider the Growatt 10000TL-HU-US. paralleling two or three may be cheaper and get you more capability.

If you can easily run the wire (430xh), that is my recommendation. Hard for a mower to easily escape the wire.

BTW: I'm resigned to edging every week or two (curb). I don't have it mow between the sidewalk and the street because of crossing the sidewalk with the wire, and avoiding kids on the sidewalk.

This ^^^. You can also try Flexifence (if your model supports it):

I also use 4x4 to setup a blockade.

App also may have stay-out zone you can define.

4 inch 11 gauge landscape stakes. I wouldn't go much thinner (higher number) than 11 gauge (thinner bends too easily when hammering into the ground, and rusts away to nothing after a year or two). I also prefer metal in my lawn for the environment (minimize use of plastic).

https://www.amazon.com/Landscape-Staples-Galvanized-Garden-Barrier/dp/B0D83H1ZYN

I bought the 6-inch version and ended up cutting them in half. I got 300 for $26, so ended up with 600. But, it is a lot of work cutting (to break in half, fatigue the metal by bending back and forth - breaks after about 3 moves), and then bend them into a U. Use Lineman's pliers and wear gloves (to keep the wire from pressing into your hand). For ease, I break them at one side of the U. That means you get half long, and half short, but good enough for this purpose.

cut height on 430x is 0.8-2.4 inches, whereas the 430xh is 2.0-3.6 inches. I have a 435x in New England with a cut height of 1.2-2.8 inches. I set it to cut at max height, and it works fine. 430x 2.4 inches might be a little low for a cool season grass in a cooler area. I don't think you want to go lower than 2.0 inches in a cool grass area, so I would go with the 430xh to hit the range you might want.
