Smart Battery Box Series 2

G'day Rod,

The Engel Smart Battery Box can be connected to solar by an Anderson plug, the battery box does not have its own regulator so your solar panel would need to have its own regulator in-line. You can find the Anderson plug outlet on the side of the unit. 

G'day Jez,

The Engel Battery Box is not internally regulated for solar. An external Lifepo Lithium regulator is required. 

G'day Joe,

I've not been able to get a direct answer from Engel however everything in their User Manual stipulates they are only compatible with batteries up to 140AHr so unfortunately, I don't think it's going to be compatible with your 145Ah battery.

G'day Casey,

If your fridge and lights both have a normal 12V cig-plug you could grab yourself a double cig-plug adapter from somewhere like Jaycar, this should be fine as long as you don't exceed the limit of the adapter (usually around 10AMP). Alternately you could grab an Anderson to 12V cig adapter and run one of them from that output.  

G'day Lyn,

The Engel Smart Battery Box Series 2 is just an inverter box so doesn't actually have an internal battery, you would need to purchase a deep cycle battery separately to use in the unit. If you're needing to run a 12V fan while away from your vehicle then you could grab a CoolPower RAPS44 Power Pack, Goal Zero Yeti 150 or Companion Power Pack 44Ah depending on how many amps your fan draws and how long you'd like to run it for.

G'day Adrian,

Providing you have a regulator or charge controller on the solar panel, you should have no issues charging simultaneously. 

G'day Annette,

You can use as large a sized solar panel as you like with the Engel Smart Battery Box Series 2, as long as the solar panel has an inbuilt charge controller, which most will have these days.  Hope that helps.

G'dau Greig,

I've just double checked this and I can confirm that the Smart Battery Box Series 2 comes with a 12v and 240v cable.

G'day Billy-Ray,

Yes, you absolutely can charge and discharge at the same time. Its really important to note though, if charging your Engle Smart Battery Box Series 2 with solar panels, the charge goes directly to the battery and NOT through the Smart System.  In this case, you will need to use any solar system with a regulator.

G'day Darren,

The maximum continuous power the Smart Battery Box can tolerate 300 watts, with a spike output power of 900W. So in short, no you won't be able to charge a 400-watt hour lithium bike battery with this unit.

G'day Steve,

There is both a standard cigarette style 12V plug and an Engel 12V socket, so there won't be any need to replace or remove any of the ports.

G'day John,

Yes, you can charge the Engel Smart Battery Box Series 2 using a solar panel. You'll just need to make sure your solar panel has a regulator and can connect via an Anderson plug.

G'day Tom,

We've double checked with Engel, and the Smart Battery Box Series 2 can be used with LiFePO4 batteries. The lead supplied will be able to charge all battery types used in the unit.

G'day Steve,

I've just consulted the tech experts and the Engel Smart Battery Box Series 2 doesn't have an overcharging protection mechanism so you'll need to use it with a solar regulator. Most Solar Panels have these inbuilt and attached to the back of the panel.
