Hello Anthony,

I really wish you could, but the PowerMax 30A RV Power Center and Distribution Panel with 45A DC Converter # PM47VR is not directly compatible with your Goal Zero L500 in the way most people hope.

The PowerMax converter is designed to charge a traditional 12-volt RV battery bank, whether lead-acid or lithium, that is wired directly into an RV electrical system. A Goal Zero L500, however, is a self-contained portable power station with its own internal battery management system and specific charging requirements. It is not meant to function as a direct replacement for a hard-wired RV house battery.

You should not connect the 12-volt output from the PowerMax converter directly to the Goal Zero expecting it to charge properly. The charging profiles and current limits are different, and doing so could cause improper charging or potential damage.

Instead you will want to use a battery like the Go Power Sun Cycle Advanced Lithium RV Battery - LiFePo4 - Bluetooth - Group 24 - 12V - 100 Amp Hour # GP99QR.

What kind of RV is this going in? Do you do a lot of boondocking? Any fun adventures you are looking most forward to this year?

I am converting a 5x10 utility trailer into a toy hauler for my Adventure Motorcycle. I will be doing a fair amount of boondocking and was recommended to get the goal Zero 1500. Apparently, if I understand your response, I will need a deep cycle battery bank and an inverter or one of the combo power boxes specifically to power the 12 volt accessories. I would assume the goal zero will provide electricity outside of the trailer? Or would I be able to plug the goal zero into the external 20 amp plug of the trailer? I plan on having 30 amp and 15 or 20 amp external plugs. Thank you for your exceptional and detailed response to my question. I am just getting my feet wet with the trailer life. Thank you, Anthony

@AnthonyM That sounds like a fun build. A 5x10 toy hauler for an adventure bike is a great lightweight setup for boondocking. You would not need a separate deep cycle battery or inverter if you go with the Goal Zero 1500. It already has a lithium battery, built-in inverter for 120-volt power, and 12-volt outputs. It is basically an all-in-one power unit. Yes, you can use it to power things outside the trailer directly. You can also plug your trailer’s 15-amp or 20-amp exterior inlet into the Goal Zero’s 120-volt outlet with a standard cord. That will power your interior outlets like you are plugged into shore power. If you add a 30-amp inlet, you can still use it with a 30A to 15A adapter. Just remember you are still limited to about 1500 watts, so you will need to manage what is running at the same time. If you are mainly running lights, charging devices, maybe a fan or small appliance, the Goal Zero is a simple and clean option. If you plan to run bigger items like a microwave or air conditioner, a traditional RV lithium setup would give you more flexibility long term.

@KateF If I wanted to have some 120v outlets close by could I just connect 3 outlets in parallel and plug the origin into the 120 ac plug of the Goal Zero? Would I need a breaker box and circuit breakers? I am so appreciative of your advice.

@Anthony I would not recommend wiring three outlets together in parallel and plugging that into the Goal Zero. While outlets in a home are wired in parallel, they are protected by a breaker panel upstream. Simply tying outlets together without proper circuit protection is not the safest way to build out your trailer. If you want multiple 120-volt outlets installed inside the trailer and done correctly, the right way to do it is with a small breaker panel and distribution system. That’s where something like the Progressive Dynamics 4000 Series Mini RV Converter w/ Charge Wizard and AC/DC Distribution Panel # PD4045KA comes in. It gives you a proper 120-volt breaker panel to protect your outlets, and it also includes a converter to charge a dedicated 12-volt battery bank for your lights and other DC accessories. In that setup, your exterior 15-amp or 30-amp inlet would feed the # PD4045KA. From there, your outlets would be wired to individual breakers, and your 12-volt circuits would run off a real battery bank. That is the safe, RV-correct way to build a permanent system. If you plan to stick with the Goal Zero as your main power source, the simplest and safest route is honestly just using a heavy-duty power strip or extension cord rather than hard-wiring outlets. Once you move into permanent wiring, a proper panel like the PD4045KA and a dedicated battery bank is the better long-term solution.
