DIY Solar Generator / Portable Power Station

Product overview (portable DIY solar generator / power station)

A modular “Gen 2” rigid-box portable power station built around two 12V 100Ah batteries and a 2000W inverter. It includes solar charging and battery charging, with emphasis on cooling, monitoring, and expandability.

Key components & features mentioned

Modular Gen 2 rigid box

• Upgraded from Gen 1: “more rigid”
• Components are tightly packed and secure (no rattling)
• Fuses organized by function

Battery bank

• Uses two 100Ah 12V batteries (described as ~89% full during the overview)

Inverter / charging system

• 2000W power inverter
• 20A charger (built-in)
• 40A MPPT solar charge controller

Cooling / ventilation

• Four fans total
  • Two 60mm fans controlled by a thermostat (setpoint adjustable)
  • Two 50mm fans with variable speed
• Heat exhaust routed outside the box via an exhaust port; hot air exits the side
• Climate notes (speaker remarks):
  • In Arizona (warm climate) they use more aggressive cooling
  • In Alaska, it may be “overkill”

Control panel & monitoring

• 5-button control interface and a gauge showing battery/charge information (e.g., solar input, charging status, current draw)
• Bluetooth remote (Renogy BT2) for phone monitoring (“stats” while traveling)
• A license-plate-style light for night use / reading the charger

Power outputs / ports

• Two Anderson 30A plugs (each with separate fuses)
• Cigarette-lighter style output
• USB outputs

Expansion / add-ons

• Mentions a later-addable optional component (shown as optional in the system concept)
• Provides room for more charging capacity via a removable add-on area
• Can be reconfigured toward a 24V system
  • Renogy “can do 12 or 24,” but would require:
    • series wiring for batteries
    • swapping to a 24V inverter and 24V charger
    • possible 12V conversion for accessories

User experience / performance observations (as claimed)

Charging behavior (built-in 20A charger)

• Charging indicator:
  • Red = charging
  • Green = fully charged
  • Then it shuts off automatically
• Example test measurement: about 19.3A pulled (near the “20A” capability)

Noise

• Fans are “not too loud” once enclosed
• Fans ramp up under higher thermal load

Thermal testing

• Fan behavior demonstrated with a heat gun
• At high heat:
  • inverter fans and airflow increase
  • heat appears routed out of the box
• Test claims:
  • no wires getting hot
  • system “runs really good”

Inverter load examples

• With heat load on the inverter:
  • “low” test: about 40A DC amps
  • “high” test: about 84A DC amps
• Heater scenario:
  • Low heater: about 78A DC amps with inverter fan kicked on
  • High heater (~1500W rated): settles around 100A+ DC amps
• Power estimate method:
  • cites amps × volts to estimate watts
  • referenced about 1300W at that moment (from ~100A at ~13V)

Solar input

• Uses six Renogy 100W panels (claimed 600W total)
• Adjusted panel tilt toward the sun
• Measured solar draw: about 35A
• Battery gauge rising quickly (e.g., ~964 → 965 reading)

Expandability / “more capacity” add-on (major comparison to base setup)

• Adds an optional 45A charger plus an extra 40A solar controller in an add-on module
• When the 45A supply is plugged in:
  • measured around 43.7A
  • described as functioning like an RV-style charger + power supply for DC loads
• Capability demonstration (noting over-manufacturer guidance):
  • Plugging the add-on into the built-in 20A charger is described as over the manufacturer’s recommendation
  • Result measured: about 62A charging current possible “in a pinch”

---

Comparisons / alternatives mentioned

Gen 2 vs Gen 1

• Gen 2 described as “much better” due to increased rigidity

Cooling strategy by climate

• Overkill in Alaska (too much cooling)
• More appropriate in Arizona heat

24V system future option

• Reconfigure the same platform for 24V (with component swaps)

---

Pros (unique points mentioned)

• Modular, compact Gen 2 design with secure internal mounting
• Multiple charging options
  • Solar (MPPT), built-in 20A charger, and optional 45A charger add-on
• Strong cooling design
  • thermostat-controlled fans + variable-speed fans
  • exhaust directed out of the box
• Monitoring and usability
  • gauge display of battery/solar status
  • Bluetooth monitoring (BT2)
  • night light and organized control buttons
• Multiple output options
  • Anderson 30A x2 (fused), cigarette-lighter-style, USB
• Expandable capacity
  • documented method to add extra charger/controller space
• Tested performance claims
  • high-current charging and inverter loads demonstrated without overheating wires

---

Cons / risks (unique points mentioned)

• Over-manufacturer caution
  • Running the add-on charger into the existing 20A charger is explicitly described as over the manufacturer recommendation (though tested)
• No single main power switch
  • multiple internal switches/controls; user must manually connect/disconnect inverter/PV
• Room limitations
  • “No really room for much of anything else” due to tight packaging and airflow needs

---

Overall verdict / recommendation

Best fit: DIY users who want a high-power, modular portable solar power station with strong cooling, monitoring, and expansion paths.

Recommendation: Likely a good choice for heavy loads (inverter usage) and fast recharging, especially if you’re comfortable with DIY setup and potentially reconfiguring (12V/24V). Be cautious with the over-recommendation charging combination, and expect the design to be tight/limited for future additions.
