Make sure all your solar cables are fully connected, use volt meter to test each string. Make sure the connectors snap all te way in. Once all stringd connected, flip all fuses to off and check to see output to controller light is on, turn off and on and check each string individually. I found gauge of wire a bit thin and upgraded fuses to 30 Amps. Have used box 3 years at full 2400 Watt capacity with no problems. **Q: Is it just a plug n play or does it come separate** A: No you need to prep it. There is some wiring that needs to be done in the box before use. **Q: If the ground wire is attached from the combiner box to the grounding rod, do the panels still need to be grounded?** A: If the panels are grounded to the same rod, I suppose you do not need to add a second grounding. In case of an electrical storm, the grounding of the combiner panel is of the upmost importance. I have used this connection to ground also the control charge, inverter and the DPS **Q: Does this connect 4 100w panels in series or parallel?** A: If you connect each panel (string) individually to the PV Combiner Box, the panel strings will be combined in parallel. You can also connect two panel pairs or all four panels in series before connecting your four panel array to the PV Combiner Box. However you connect your four panel array to the PV Combiner Box, keep in mind that each string (up to four maximum) must be limited to 10 Amps current as specified by Eco Worthy. Also take note of the Eco Worthy specifications for maximum allowable voltage. Parallel panel connections multiply current from each panel and series panel connections multiply voltage from each panel. If you are using the four panel array to charge batteries, you should also use a charge controller. For a 400 Watt array, you should consider a MPPT Controller, which would work best with a higher input voltage achieved with series panel connections. Note, however, most smaller MPPT controllers are limited to 100 Volts input. Lastly, before selecting parallel or series panel connections, consider partial shading of the panels. If you expect partial shading, parallel connections between panels would work best. Refer to your panel manufacturer recommendations and panel specifications. Also, always take care to make sure your wire size complies with applicable codes and specifications for current and voltage. ## Frequently Bought Together - ECO-WORTHY 4 String PV Combiner Box with Lightning Arreste, 10A Rated Current Fuse and Circuit Breakers for On/Off Grid Solar Panel System - ECO-WORTHY Solar Crimper Tool Kit 13 PCS Solar Tools - a Crimper, 10 Pairs of Solar Connectors, 2 Pairs of Solar Connector Spanner Wrench for Solar Panel Cable Assembly and Installation - BougeRV 44PCS Solar Connector with Spanners IP67 Waterproof Solar Panel Cable Connectors Male/Female 22Pairs(10AWG) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.at/products/67987657-eco-worthy-4-string-pv-combiner-box-with-lightning-arreste](https://www.desertcart.at/products/67987657-eco-worthy-4-string-pv-combiner-box-with-lightning-arreste) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-09-07*
