    12V/12Ah Solar Generator Charging

    Switch to an MPPT charge controller. As @Rednecktek suggests, connect the 14.4V car charger directly to the battery. The BMS will protect the battery.

    Something I wish Will would test to see if viable long term

    I always wondered why Montek haven't continued to build portable power stations? I had an email conversation with them many moons ago re future products but they eventually stopped responding. I thought they had the potential to build on the success of the Montek 1000.

    Delta 2 Ecoflow bluetooth / wifi reset

    I would suggest reaching out to customer services via email or Twitter for a resolution. I don't own an EcoFlow unit, but I think it needs WiFi connection before pairing via Bluetooth. I may be wrong though...

    Renogy software VS Rich Solar Software for MPPT controllers...

    When using Renogy's MPPT Boost CC I experienced many issues with the BT-2 bluetooth module and the Renogy app. The app was - if I'm being honest - pretty pathetic (considering the standard of apps available from other manufacturers). The bluetooth connection regularly lost connection, making it...

    EcoFlow Delta Max 2000 - 12V DC Outlet

    I'm sorry to hear the issues you're facing with your Delta Max. In response to your first question, I have heard and received a number of complaints from my viewers re EcoFlow after-sales customer service. Whilst it's important to remember that the quality of customer service can vary between...

    EcoFlow Delta Pro Discussion

    One of my viewers reported a similar experience. Customer service has been non-responsive. I understand some units naturally develop issues despite QC. I get that. But nothing can be more frustrating than spending hundreds if not thousands on a product, only for the support to leave you hanging...

    EB-240 problem

    I'd be on to customer services right away. Keep trying to get through via email/social media. Best of luck.

    What is the logic in a 2400W output solar generator… with a 1500Wh battery?

    AllPowers have certainly been around in the power station marketplace for some time. But there have been notable concerns regarding the quality of their products and customer service. A majority of their units, including the Monster series, have proven unreliable and known to have multiple...

    Anyone have first hand knowledge about the 3 Solar Generators that have made my list?

    I have the Jackery 2000 Pro. Robust unit, though Jackery remain loyal to Lithium NMC chemistry cells. Solar setup can be cumbersome. I have a review with pros and cons of the unit (see below). I'm on no position to comment on the EcoFlow Delta 2 Max or Bluetti AC200 MAX as I have no experience...

    Looking for recommendations for an all-in-one solar generator for a variety of uses

    There are a number of power stations available in the 2000-3000Wh category. My advice would be to stick to brands with a reputation of good build quality and customer service. I would happily pay a bit more for the added peace of mind of a reputable manufacturer with a track record of standing...

    3kW Portable Solar Generator

    If you ship to the UK, I'd be interested in evaluating a unit on my YouTube channel. I have some recommendations too. I believe these suggestions can help improve the unit further.

    Jackery Explorer 500 BMS identify/replace

    Have you emailed Jackery re the BMS? Perhaps they can shed some light on a) the BMS and b) how to resolve the issue at hand. Techman

    Jackery 2000 to MC4 connectors 1200 watt

    I've uploaded my evaluation, pros and cons of the Jackery 2000 Pro today. I discuss the DC8020 connector and the challenges that come with it. There are also a few suggestions at the end which I have forwarded to Jackery too.

    Bluetti EB70 solar panel/s to get closest to full 200w charging??

    It may be difficult to get 300W as there is a current limit of 8A. You may be able to get a bit over 200W but I'd imagine that's just about it. I'm now curious as to how much you can push into the EB55. I'm away for a few weeks, but when I return I may experiment max input at various voltages on...
