Zeus 24V 4kW Low Turn On (LTO) 3.15 Alternator with Isolated Ground

The ARCO Zeus 24v 4kW LTO alternator turns on at lower RPMs, runs cooler, and provides more power than older designs that are larger and heavier. This alternator continuously generates over 1.4kW (51 Amps) at just under 1,500 RPM and almost 2.4kW (87 Amps) at 2,000 Alternator RPM. Put in real-world terms, a marine diesel engine idling at 750 RPM with a 2:1 pulley ratio is generating over 1.5kW (55 Amps), and a Mercedes Sprinter at 750 RPM with a 3.21:1 ratio is generating over 2.5kW (91 Amps)!

The ARCO Zeus 24v 4kW alternator turns on at lower RPMs, runs cooler, and provides more power than older designs that are larger and heavier. The newest generation of 24V performance has arrived.

Competitor’s 24V alternators utilize a 12V rotor and field current which is less efficient and limits output at all RPMs. ARCO utilizes a native 24V rotor and field current. This results in our 24V alternator running cooler than competitor’s 24V alternators, having a direct impact on the alternator lifespan.

Beautiful Solar Angel Garden Statue
I honestly teared up a little when I opened this because it’s even more beautiful in person than I expected from the listing. The angel design with the birds perched across the arms is peaceful and eye catching, and once it’s placed in the garden it really becomes a focal point. I positioned mine in a sunny spot and surrounded the base with a few decorative stones to help hold it in place since the statue itself is fairly lightweight. The solar feature works great, I’ve had it outside charging during the day and the birds automatically glow at night with a soft warm light that looks really pretty once the sun goes down. It gives off a calm, cozy glow that makes the yard feel really inviting in the evenings. The resin construction seems durable for outdoor use and overall the detail is really nice for the price point, though if you look very closely you can see a little bit of glue around the birds. Once it’s set up outside though, those little details fade away and the overall effect is just beautiful. Overall I’m really impressed with this piece and it’s a lovely addition to the garden.

Poor quality
This is really cheap looking in the daylight but it is quite pretty when it lights up at night. I wish the birds weren’t multicolored and could match the white tone of the angel (what makes it look cheap), but when it lights up at night you don’t see the multicolor. It’s just a beautiful glowing soft white. My problem with this is that it tipped over in a light breeze because it’s super light weight and several of the birds popped out and are hanging by their wires and will not stay in after trying to pop them back in. I will probably have to crazy glue them back on. If I put this figure in a sheltered place, then it doesn’t get the sunlight it needs to light up at night. And after the fall, it’s not lighting up well. I’m not sure if that’s because it didn’t get enough sunlight when I sheltered it or some of the wires became dislodged. This is not a good item for a garden. It has no weight to it to make it stable outdoors. *** Additional added note - after the fall, this statue completely stopped working and doesn’t light up at all. A waste of money!
