Victron Energy MPPT WireBox-M Victron Energy BlueSolar and Smartsolar MPPT Solar Charge Controller - for 100V 3050A & 150V 35A

**** The Victron Energy MPPT WireBox-M has received strong praise from customers for its effective design and high-quality Construction, making it a valuable addition to solar charge controller setups. Users have noted its durable nature, highlighting that it provides excellent protection for cables and terminal entries, especially when installed in less rigid environments such as RVs or outdoor storage spaces. One common theme among users is the importance of ensuring the correct size of the WireBox-M is selected, as there are multiple sizes available. Users who initially ordered the wrong size were pleased with the return experience and found the correct variant offered a perfect fit. The ability to secure wires and cover terminals adds a layer of safety, which many have recognized as essential, especially for mobile solar setups or in places with daily foot traffic. However, several reviews pointed out certain drawbacks. Users felt that the WireBox-M should ideally have been included with the purchase of the Victron charge controllers rather than being sold separately, given the safety and functionality it provides. The installation instructions were also noted as lacking detail, particularly concerning the need to replace existing screws with those provided with the WireBox-M during installation. Overall, despite minor criticisms regarding pricing and instructions, customers are satisfied with the performance and reliability of the WireBox-M, viewing it as a necessary accessory for a complete solar charge setup. **
