Zeus 24V 4kW Low Turn On (LTO) 1"-2" Single Foot Alternator with Isolated Ground & Zeus High-Energy Alternator Regulator

Zeus 24V 4kW Low Turn On (LTO) 1"-2" Single Foot 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 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 competitors’ 24V alternators, having a direct impact on the alternator's lifespan.

Zeus High-Energy Alternator Regulator

ARCO’s Zeus is the only high-energy external alternator regulator to feature Bluetooth and a native app (on IOS and Android) allowing for easy installation and configuration. With its intuitive interface, you can access information on your system that you never had before. This information will enable you to regulate your system and optimize your battery charge and alternator output, resulting in a safer experience while protecting your energy system investment.

Zeus is the only alternator regulator that can read 2 shunts at a time (the battery shunt and alternator shunt). This feature enables Zeus to react to inputs from the battery current/temperature and alternator current/temperature.

Through the ARCO Zeus application, you are in good hands. Your data is automatically logged and can be shared with your technician to troubleshoot your system remotely. You can even import your remote technician’s configurations. 

Zeus optimizes battery charges for 12-48 volt systems. Whether you are using Lithium (LiFePo4) batteries or lead-acid Deep Cycle batteries, Zeus has you covered with its pre-set battery libraries and configurable menus to optimize your charging profiles. Zeus manages a complex set of inputs by giving you easy-to-understand options.

Zeus also takes into consideration the power of your engine and allows you to configure the alternator’s power take-off from the engine by managing the field, or duty. An advanced feature of Zeus is that it can turn your engine into a dedicated generator with the press of a button, whereby it focuses the alternator’s performance on the creation of energy to replenish your battery bank quickly.

Consistent with Zeus’ ease of use, Zeus is the only alternator regulator on the market that comes with alternator/battery harnesses and 2 thermistor harnesses, without an additional charge, saving users money and time from sourcing harnesses.

Features:

  • Secure Bluetooth connection
  • Harnesses, Thermistors, and NMEA 2000 kit included
  • Monitors the state of charge
  • Can turn your engine into a dedicated generator with generator mode
  • Pre-set battery libraries

Makes moving your umbrella around a breeze.
Size: 100LBS
This is best idea in umbrella stands. Decent price. I love that the water intake/release is on the side. Many are on top of the stand. Doesn't leak. Easy to move around and easy to put together with the included tools. I have 2. One for a very heavy 10 x 6' umbrella, and the other for a very light 1/2 round umbrella. Works equally well for both. One tricky part the instructions don't include is that is parts F and J are 'in place' in the base and you need to remove them to re attach them to the cylinder, or what they refer to as the "stand pole". So, if you are looking for parts (and I did this twice), just remember you will find them on the underside of large plastic umbrella base. Both are black, and so not immediately apparent. Love that there are two locking wheels and they include an extra screw. IKEA could learn a few things here.

Hold my umbrella & watch this!
Size: 100LBS, Size: 100LBS
This product does a fantastic job of keeping our umbrella perfectly vertical. We previously had an all metal one which cost over $100 and fell over all of the time. I love the fact that it can be filled with sand and water to ensure it does flip over! We opted to just use water and it is performing flawlessly! The wheels make it easy to move or they can be locked in place. The assembly was very straightforward and took about 20 minutes. I would buy another one if we need it for our second umbrella.

Great stand for portability, concerns about durability
Size: 155LBS
This is great and lightweight for easy maneuverability when not filled. It is extremely sturdy when filled and the locks on the wheels keep it in place. I use this with a Purple umbrella and it's great. My one complaint is that the umbrella has developed a bit of a lean after several months of use so I don't think this will hold up in the long run.
