Hi all, I've recently set up a 2kW inverter with a single 130Ah battery and this is charged by a single 170W solar panel. The design purpose of my system is to allow occasional use of power tools or the shop-vac in my garage. The original system I put together had poor quality cables bundled...

I've got a battery with SAE lead battery terminal posts that I want to protect with MRBF "cube" fuses. Since the primary purpose of these is to reduce the risk of a metal tool short-circuiting the battery terminals, I intend to fuse both the positive and negative terminals. "B" end of the...

Hello all, I have a simple setup with a single 120W monocrystalline panel, a charge controller and a 130Ah lead-acid battery. There's also an inverter which I only turn on as needed, e.g. to run a power tool. After working adequately for 5 months or so, I found that my PV output is displayed...

I'm looking for a nice quality fuse block, but I don't want to commit to crimping blade connectors or ring terminals onto everything. I really would like to connect in bare wires and just screw them down. I'm finding it very difficult to find... anything that doesn't rely on these crimped...
