    Which MPPT is easiest to reconfigure?

    I'm going to be running two systems on my boat- 200w at 12v feeding a lead-acid bank, and a 600w, 32v PV array feeding the LFP. The smaller system is primarily equipment that is only used when actually sailing, e.g. autopilot, instruments. Once I am anchored up I may want to tap in to that extra...

    Old and new panels

    I've been reading up about mixing different sizes and specs of panels and getting fairly confused. I've already got a 100w 12v panel, but want to upgrade to a total of around 800w. I'd also add a new MPPT. If I buy more 12v panels and want to run everything through the same SCC, should I buy the...

    280Ah 12v yacht domestic system

    I'm trying to put together a 12v 280Ah system without breaking the bank or over-complicating things. It's as a standalone house bank on a yacht, charged by 60A solar (and if necessary, 30A B2B from the engine/SLA). It will power the fridge, inverter for the galley, and a few smaller loads, but...

    Options for LVD protection for an inverter

    I'm planning on a 12v 280Ah system, and want to run some 240v equipment- the most demanding being a 1600w induction hob. So I'm planning on running a 2000w PSW inverter at least. Ideally I'd like to be able to run as much 240v as the batteries can safely take, but 1600w is the bare minimum. I'm...

    Will this system work?

    Trying to narrow down on my design. Here's what I'm thinking: 800w PV->60A MPPT Epever-> 4S 280Ah with Daly 100A BMS -> 220A Victron Battery Protect -> 2kw Renogy PSW inverter All at 12v. Smaller loads will run straight off the BMS, not through the BP. Loads will include a Sterling 30A B2B...

    BMS For Dummies...

    OK to show just how new I am to this I have some *really* basic questions about battery protection, to see if I'm understanding this properly. 1- simplest option seems to be use the BMS itself as the cutoff device on both charge and load sides. 2- better is to use the BMS to trigger separate...

    Two systems, one boat

    Looking for any feedback and advice on my ideas on upgrading the electrical system on my yacht. Currently I have 2x110Ah FLA house bank and 1x110Ah SLA engine start bank. Connected through a 1-2-both isolator. Charging sources are the alternator, plus a Marlec PWM charge controller. Originally...

    dc-dc vs inverter charging

    Hello again! If I want to charge LFP from a lead-acid bank, or vice versa, it seems the two options are a) DC-DC charging; b) an inverter and AC charger. As far as I can tell, all of these pieces or kit are about 85% efficient, so going via an inverter works out at 72%. But the huge advantage of...

    Charging mixed battery types from PV & alternator

    Hopefully this is a very easy one to answer. If I have a lead-acid bank alongside my LFP, how do I set up the charging from both alternator and PV? The MPPT controller I am planning on installing (Epever Tracer) can be configured for various battery types, but whilst it can handle two banks I...

    Powering a 12v Trolling Motor

    I'm trying to get to grips with LFP batteries and thought I could dip my toe in the water by installing a small pack to power my trolling motor. I'm going to use the motor on a small tender, and would be quite happy with a full throttle duration of 20-30min- it''s just for getting to and from a...
