The unused Sydney spaces that are prime real estate for solar

“While central business district buildings might cover only 5 per cent of their energy needs through rooftop solar, industrial estates could produce between 500 per cent to 1000 per cent of their energy requirements, creating substantial excess power that could benefit nearby residential areas, including apartment buildings that currently lack access to solar,”

#US #solar just had a record-breaking #Q1 but the GOP bill could wreck it
According to the new US Solar Market Insight report from SEIA and Wood Mackenzie, the industry installed 10.8GW of new #electricity-generating solar in Q1 2025, with solar and storage making up a whopping 82% of all new capacity added to the grid.
New #tariffs and “#BigBeautifulBill” passed by the House that would gut clean energy tax incentives are injecting serious uncertainty into the market.

The middle section has big AIMS 4kW charger/inverter that will be off most of the time. I’m using its big beefy terminals as an additional 12v system buss bar. I can power it up if I need to run big power tools with high surge currents like an air compressor. And I can connect it to camp’s AC power if I need supplemental battery charging.

Below that is my primary inverter. Renogy 2kW. It’ll be on all the time now (just 10w idle power usage), but there’s a remote on/off switch in the trailer if I need to conserve.

These go straight to the 12v system buss bars. I’ll probably add fuses to protect that wiring in the future, but the fuses in the inverters should do the trick for now.

The negative side of the system buss bar goes through a Victron 300A SmartShunt then to the Dumfume 300Ah LiFePo4 batteries connected in parallel. The positive side goes through a battery disconnect switch, then a 200A fuse, then the batteries. The batteries have a 200A BMS that will disconnect if current exceeds 200A, cell voltage exceeds limits, or temperatures are too high or low.

@crinstamcamp By coincidence I'm working on the design of the electrics for my new off-grid home.

I'll have 230V 13A outlets all over the place but will also be running a parallel 24V DC feed for lighting and ELV outlets. Lots of USB / USB-C PD for laptops, clocks phones etc to run off the 24V.

I'm going to use EV1327 wireless switches as DC lighting has improved massively the last few years. I'm working on a simple CH32V003 design to dim lights. Will be open sourced.

Now that it’s light out, and I’m not exhausted, here are some better pictures of my new solar cabinet with descriptions.

Each series pair of panels comes in and goes to buss bars to be paralleled. There’s room for one more pair if I can figure out a good means to mount them securely atop the trailer.

This then goes through a 1000V 50A DC breaker that doubles as a solar panel disconnect before feeding the Outback Solar FM60 charge controller.

The panels are 325W with 45Voc and 9A Isc. The FM60 has 150V max input, and 60A max output. With an expanded 2s4p, the most the breaker and charge controller should see is maybe 110v and 40a.

The FM60 output then goes to 12V system power buss bars. I have a 150A DC breaker for that connection, but I’m out of beefy wiring to connect it. Almost all the 12v wiring is left overs from our old camp solar system. I plan to replace it with better wire and connectors and a neater layout eventually.

I left room in this top section for another charge controller on the left and an AC breaker box on the right.

Lithuania bans remote Chinese access to #solar, #wind, #storage devices

Guess who bought just another old #PV module to build just another #offgrid #solar system...

AI slop:

From the panels on my roof,
To the inverter in my booth,
I’m designing my solar proof,
Living green’s the living truth!

Yeah, I’m feeling sunny today,
Got my panels ready to play,
Gonna harness that solar ray,
Watch the power come my way!
